Spooky eyes - halloween Eyes assembly with schematic and configuration

- This is my version of a project I saw mentioned on a forum site. It is originally by Adafruit, and also reworked by Sudomod.
The video shows the hardware assembly from packaged parts to a working pair of "eyes".
The schematic diagram and the config file, adapted to work with the Seeed Xiao and that schematic, are here:
robert-jenkins.co.uk/site/inde...
I must stress that the concept and brilliant software to display the numerous eye variations are all their work and the original articles etc, are linked below.
My version uses a different microcontroller module to the ones mentioned in those articles, which appears to be cheaper and easier to find at present, a Seeed Studios XIAO which uses the same CPU as the Aruinos mentioned in the other project articles, so only needs the appropriate library installing in the Arduino IDE to be fully usable.
Edit - Be sure to get the Xiao version with the SAMD21 (ARM M0) MCU - Since I made the video, Seeed have released other Xiao modules with different ICs / CPU types, which may not work or may require different program settings - I do not have any to try.
The video thumbnail shows the pair built during the video, stuck in to a plastic skull with strips of tape across the back of the displays, plus another pair unmounted.
For the software side, see the original projects and software from these links:-
The original Adafruit project:
learn.adafruit.com/animated-e...
And the program ("sketch") for their version:
learn.adafruit.com/animated-e...
Sudomod's variation, which moves each eye independently, allowing two display in parallel on each channel, so two pairs of eyes using one MCU :

Update - apparently some people have had problems with the links to the original files; a full project file with my config is here:
robert-jenkins.co.uk/site/ima...
And for the Seeed MCU I used, their Wiki page with details on the device and instructions for adding their library to the Arduino IDE; see the section headed Software, about half way down the page:
wiki.seeedstudio.com/Seeeduin...
The plastic skull used in the video was from a high street shop, "Wilco" I believe.
The robot face section is a 3D printed part from Gael Langevin's "Inmoov" robot design:

Hi Robert, managed to play around with the 2 eye settings in the config.h and now all is well. Now it’s working I’ll explore the led and other software settings. Thanks for inspiring me.😀
Hi Colin,
that's great - sorry I did not reply earlier, a bit busy at present.
Which screens did you end up using, the 240x240 or the originals?
@@RJTC Hi Robert I eventually used the exact same TFTs in your project.
Hey Robert my lcd eyes worked a treat , i used an esp8266 found was very easy to sort as the seeds was just having issues with trying to get the com port to stay on while uploading the sketch , what i really want to do now is add a servo inside to make the jaw keep moving as well with a sg90 servo , i just do not know who to add to a sketch , on some skeletons i want lcd eyes and servo jaw , and some props just blinking led eyes with jaw , i just do not know how to define a sketch for either .
Thanks for an informative video, I have started using round 240x240 screens, would the eyes scale to fit?
It could be done, but I'd not advise it - as there is just a serial (SPI) data feed to the displays, the frame rate is rather limited. Trying to update almost four times as many pixels would reduce the frame rate by a similar ratio.
If the existing displays use 16 bit colour, each image frame update to each display needs around 100KB of data.
The 240x240 ones would need 350KB each per frame, so I'd estimate under three frames per second, rather than the roughly ten or so with the 128x128 displays.
Larger screens are superb for normal text and slow-changing graphics for information and control interfaces etc., but it quickly gets to the point you need a parallel interface to to get acceptable video of animated image frame rates with even moderate resolution screens.
I am looking at using a 480x480 screen on a project, but that will use the DSI video interface on a raspberry pi so be handled directly by the GPU, rather than through a peripheral interface. [If I can get it to work - not had time to try yet].
Hi Robert I have now constructed a set of eyes and they are sort of working. There are multiple eyes on each screen at what looks like 45 degrees with the top part of the screen not being used. Which ino did you use Adafruit or Sudamod? - I am close but some help needed Thank you
Hey Colin wonder if you could help me out , programmer all set up and working did a blink test works fine when uploaded , now do i download the uncanny eyes and delete the config and copy and paste Roberts config in its place and upload it ? do i just copy Roberts config to a blank sketch and upload it ? in easy term can you help me out to upload to get the eyes working thanks .
sir this is amazing i will remake this project. Just ordered the parts.
Thank you, it's good to know people find my stuff useful!
Once you flash to the chip are you only powering these with a battery pack? Is there a way to cheat the wiring to run two sets of eyes or four displays from one board?
Once it's flashed, it only needs power - a power pack or USB power unit (eg. phone charger).
You can run two pairs of eyes, by directly paralleling two LCDs for each eye output, but they will then be exact duplicates.
Sudomod's variation (linked in the description above) allows the two eyes to move independently rather than tracking each other. If you select that and the symmetrical eye option, then each two in parallel act as one set of eyes, but without the detailed eyelid shape. That gives two pairs from one device.
Since learning of the newer Seeed Xiao versions with different MCUs, I have got one each of the RP2040 and ESP32 versions. I've not had chance to try them yet, but it may be that the ESP32 is powerful enough to two fully independent eye pairs?
It's faster and has more memory. I will post a video showing what is possible, when I get chance to experiment with those.
Excelente video amigo existos
Thank you for sharing
I am working on this with a esp32. Thanks for sharing
Go for it!
Hello Robert i wonder if you could help me out here , i have all that you have provided , i made the wires up and board , this is where i am stuck , i downloaded the board software uploaded the blink and the board light itself blinks so all working there , now the next part is where i am stuck , do i download the uncanny eyes and delete the config and copy and paste your config in its place and upload it ? do i just copy your config to a blank sketch and upload it ? in easy term can you help me out to upload to get the eyes working thanks .
Hi Dave,
yes, use the original uncanny eyes program but overwrite the config file with my version.
If you have any other questions, please let me know!
@@RJTC thanks for getting back to me on this and clears up now what i needed to know thanks .
Hello Robert, thank you for your video. I'm about to do the same but like to know if it is possible to add a IR sensor to activate the eyes and eventually some sound? thanks for your help :)
An IR sensor should be simple enough, you could switch the 5V power to the LCD backlights (rather than have the backlight resistors connected to 5V on each display). That would make the eyes near invisible when the backlights were off, but avoid delays while the CPU started up that would happen if you switched power to the whole system.
I'd not considered sound, I don't really know what sounds would be suitable? A small sound recorder/player module triggered from the IR switch could work, if you can find sounds suitable to record on it.
@@RJTC thank you for the quick reply. I'll try to make a schematic to understand. For the sound i was thinking of a laugh like halloween ;)
@@RJTC Thank you another question: can we display the eye with the display horizontally instead of vertically? where can the setting be changed?
@@gregorypierson9801 Yes, you can - see around lines 54 - 55 in the config.h file, where the display outputs are configured. The third value is the rotation setting for each display.
I've just done the same myself, when I was building the hoped-to-be animatronic head - that needed the displays mounting with the connectors facing each other in the centre, so each needed a different orientation.
These are the settings I used in that:
{ 3, -1, 1 }, // LEFT EYE display-select and wink pins, connector inwards ++++++
{ 2, -1, 3 }, // RIGHT EYE display-select and wink pins, connector inwards ++++++
@@RJTC thank you i'm progressing with this information ;) what type of external battery are you using. I saw some using lipo soldering directly on the 2 pin on the board. I'm not fan, i think a 2 pin connector is better in case on changing the battery?
Congratulations on the project, do you have a list of the components used?
Everything is (or should be) shown in the schematic, which is linked from the video description.
hi, i'm extremely new to this so it may be a silly question but what should i look up when trying to buy wires to make this?
Any thin, flexible insulated stranded copper wire should be OK.
It's often called "Hook-up wire", though that is available in many sizes. Something like 24AWG to 28AWG is probably reasonable for low current use such as with a project like this.
(Note that the lower the gauge number, the thicker the wire; 1AWG is as thick as your finger, 40AWG has the copper just 80 microns diameter!)
eg. Search such as Amazon for "24AWG hook-up wire" then look for stranded types, rather than solid.
You can also get kits with several small spools in different colours.
Hi Robert, I am attempting your build and I've breadboarded the schematic you posted and loaded your uncannyEyes sketch. It took a few times to get all the dependencies installed but it compiles without error. I have a green LED on the MCU but the LCDs are lit up solid white. Do you have any hints on what I should look for as a problem?
If you are using all the same parts, the most likely problem I can think of is a swapped connection or short, in the signal wiring between the MCU module and LCDs?
@@RJTC Thanks Robert. I believe you’re correct. I moved the breadboard around & it started working so it’s a poor connection problem. Today I’m going to solder it up & hopefully it will be stable. I did try changing the eye type by commenting out the default & Un commenting the non-scalera but it had compilation errors. Do I need to do more config modifications other than what I mentioned?
Hey Robert, just to let you know, it was the wiring. I soldered it in place and it’s working on the default eyes. I haven’t gone back to try other eyes yet. I’ll probably give that a try tomorrow. Thanks again for an awesome project. I know you mentioned standing on the shoulders of others so to speak but your video and explanation was great!! Kudos to you for putting this out there for others to enjoy!!
Hi Robert, thank you for making this so clear, as a complete beginner I will be attempting the project this weekend. I was just wondering about the power supply as I don't want to wreck it all by doing something stupid at the end. Would I be correct in thinking any 5v 2amp power bank will be sufficient?
Yes, any USB power bank or USB wall power unit should be fine - I've run them on an old half amp USB phone "charger" (which are just 5V power supplies).
How much can I increase the screen brightness with this display? I have 56R in series but it isn't great in daylight
Exactly same problem
If you get any solution ..do let me know
Hi Robert, So the eyes have been working great for my Halloween project. All the different eyes work except the dragon and NoScaleraEyes. I got "arm-none-eabi/bin/ld.exe: region `FLASH' overflowed by 13812 bytes collect2.exe: error: ld returned 1 exit status error message. It appears to me that there's not enough memory on the MCU. Am I understanding this correctly? Is there a way to adjust memory usage when compiling? I'd like to try the dragon's eyes if possible. It may be perfect for my prop.
When I get chance, I'm hoping to do a video showing building the software from scratch. I'll have a look at the alternate eyes at the same time.
@@RJTC Thanks Robert! I realize it's been quite some time since you've posted this, and I understand if you don't go back to add to it, but I'd love to learn more about the software side of the project. So, if you put the time into it, I'd surely will appreciate it!
Could I also use a more powerful esp32 or is there no need?
I know this is silly old but my question is will the Arduino "Uncanny Eyes" configuration file from the Adafruit project work on other versions of the arduino? I've got a UNO and a MEGA also id like to use 1.28inch TFT LCD Display Module Round RGB IPS 240x240 Resolution screens for the eyes..... maybe a updated video? Yours seems to be the only one who is using modern type stuff.... thank you again for your efforts on these type of videos
Not with those, unfortunately.
Most other Arduinos use small 8 bit MCUs; this needs one of the 32 bit cpu based devices such as an Arduino Due, for both the larger memory and speed requirements.
@RJTC ok where is the programing for the xiao? I've followed the links in the description but with all the extra do this don't do that is very confusing for a newbie like me. I'd like just to install the ISO that you used for the demo. No joystick just having them randomly look around is more than enough.... obtw thanks for the help
@@edsonglutes8947 Hi, I've added a link to the full project folder in the description, also here:
robert-jenkins.co.uk/site/images/Halloween_Eyes/uncannyEyes.zip
You still need the Arduino programming package, with the Seeeduino library added in, to build it and load it in to the device though.
@RJTC thanks buddy I'll try this link tonight.... I've got mine all set up per your video but it won't goto the xiao becouse of all the errors. 😮
@RJTC this is the same link as before?
Hi Robert i have a slight issue , i have made one set works fine but i brought another seeed board and they sent the wrong one , the one they sent was a Seeed XIAO RP2040 would this still work with the config ? and setting up same wires ? they refunded me on this due to not sending the same version board as used before and told me to keep the board , just wondering to save time and effort if it would still work doing it the same as the other set up .
Hi Dave,
I did not realise until today that there were now different versions of the Seeed Xiao!
The RP2040 also uses an ARM M0 type CPU, so should work, and from the Seeed wiki data the pinouts are compatible as far as the SPI and digital pins.
The only restriction I can see is that it's limited to four analog inputs, so if you wanted to use the LDR to control pupil size, you would need to change pin assignments slightly; eg. move the two chip selects along one and use the D2 pin for the analog input. That's just based on the data I can find quickly, I have no way of testing it.
@@RJTC thanks for the info as always Robert will give it a go .
@@RJTC i got the new board to blink , i then added all and got many errors , was telling me to download this or the library was missing and so forth now after all sorted before the sketch uploads i am seeing this now and totally lost , Compilation error: 'KINETISK_SPI0' was not declared in this scope , i have no clue what to do next if honest , seems every time i try to upload its error after error to this point .

@@blackdave8525 Each time you connect a different board it seems that Windows creates a different virtual com port - have a look at Ports in the Arduino Tools menu and see what else is listed when the new board is connected?
I got another Xiao module type to test, unfortunately it's the ESP32 one not the RP2040 so I can't duplicate what you are seeing, sorry. I will try building the program for the ESP32 and see what changes are required if any, and also for the RP2040 once I get one of those.
Hello i finally got the program to instal but no eyes are showing. I'm using 1.28inch TFT LCD Display Module Round RGB IPS 240x240 Resolution GC9A01 Driver, and ive read i dont need the resistors. Do you think i do or different ones? Thanx
Hi,
from what I can see, those modules are strictly 3.3V only, unlike the rectangular type I used?
5V may damage them.
That's from the datasheet for an EastRising "ER-TFTM1.28-1" which seems identical to ones on ebay etc?
They should not need a resistor as the backlight is controlled internally, it just needs the BL pin connecting to the VCC pin to turn the backlight on.
You will also have to use the Adafruit_GC9A01A driver library rather than the ST7735 library for it to function?
Hello Robert
Great stuff those projects of you
Is there a way to give me a full working arduino sketch for the seeduino board that I can use.
I soldered the "hardware" on the way you did in the youtube instruction, but for me it is impossible te create a working arduino script with the information on the internet.
Hi,
I'm not sure why the original project download is not working, but I've zipped my project folder and put it on my site, here:

Hi, sorry, I'm not sure, those are nothing I've ever seen before..
The only thing I can think of, is possibly if you are missing a library from Arduino installation?
Have a look in Tools > Manage Libraries, then in the search box put Adafruit GFX Library & install that if it's not already showing installed?
Then the same again, but search Adafruit Zero DMA and install the latest of that?
I have versions 1.11.3 and 1.1.0 respectively.
@@RJTC With your help Robert I solved the problem and now the sketch is loaded on the seeeduino board. Thnx again
Hi Robert I've tried uploading the code to the Xiao but it stops with the error that it cant find "graphics/defaultEye.h" . Am I missing something please. I'm a bit of a novice I'm afraid. Do I need it to be able to access something that I haven't downloaded. Thanks
Hi,
I've just uploaded a new video that goes through the software install & built from start to finish, hopefully that will help fix whatever problem you have?

Sir what are the components you had to be used it.
Two 1.44" 128X128 SPI Colour TFT LCD Modules; the red PCB type sometimes listed as an alternative to Nokia 5110 displays (search ebay for "128x128 lcd nokia" and you should find the exact ones), plus a Seeed Xiao M0 module and two 56 Ohm resistors. They are all shown in the video and in the schematic on my web site, via the link in the video description.
It seems there are now three different "Seeed Xiao" modules with different types of CPUs - you need the M0, with the SAMD21 MCU.
Hello! I repeated this project, but how to turn the eyes vertically like yours!!! I have eyes on the whole display!
Hi,
in the "EYE LIST" section of the config file, the last two lines in the if/else/endif;
#else
{ 2, -1, 0 }, // LEFT EYE display-select and wink pins, no rotation ++++++
{ 3, -1, 0 }, // RIGHT EYE display-select and wink pins, no rotation ++++++
#endif
The third number for each eye, zero in those, sets the rotation. Try 1 or 3 - that should rotate 90' one way or the other. They can be different numbers, to suit the LCD orientations.
If your file is already non zero there, add or subtract one to see which gives the correct orientation?
(Changing by 2 rotates 180').
Where can you purchase the eyes?
Hi Thomas,
they are 128x128 TFT LCDs, if you search for that on ebay or amazon etc. and look for the type with a red PCB and eight terminal pins (or holes) at one end, they should be the ones. This is the first example I found on ebay, just now:
www.ebay.co.uk/itm/313603434345
I use a single monitor but my eye shape is horizontal, which part do I have to adjust?

Hi Oscar,
As far as I remember, the only thing I had to add manually was the link to install the Seeed board data addons.
See step 3 in the Seeed info here:
wiki.seeedstudio.com/Seeeduino-XIAO/#software
Copy the green URL in to the additional boards part of the Arduino IDE settings, OK that page, then select Seeduino Xiau in the board manager.
If you still get errors after that, can you say exactly what error you get??
Thank you very much Mr. Robert for her quick response,
I sincerely have very little experience with the arduous language and any setback seems to me a world, although seeing your video the truth seems very simple, thanks to people like you make people like me want to get involved in this type of project.
I greatly thank you that you have a little patience because of my inexperience.
If you allow me a query and a request:
* In the electrical diagram, a 3k3 Ohm resistor appears, but the video does not show that it is included.
* Could you pass me the program as you use it, to enter it in my arduino IDE, only with the appearance of the eyes with lids that you see at the beginning of the video.
You'll excuse my ignorance and inexperience, but there's no way to get it to work.
Thank you very much for everything and from Spain I encourage you to continue with these projects, which fill us with enthusiasm to try to introduce Halloween in Spain
@@oscasun6894
I mention that at 34:15 in the video; the resistor plus an LDR (light dependant resistor) allow the eye pupil size to respond to light.
The LDR was one out of my oddments collection and I have no idea what exact type it was. I measured its resistance in average indoor lighting, which was around 3500 Ohms, so used a 3k3 to give an approximate mid-supply output with that level of illumination.
The junction of the LDR and resistor connect to pin 5 on the MCU module (Analog input 4), and then enabling the pupil size option gives the light-sensitive effect.
I will try to look at the code and post an appropriate version in the next few days.
Very good, as always very grateful, I look forward to your publication. thank you very much sir Robert
