Thanks once again for a greatly instructional video. After watching not only do you understand the principle behind it, you also have a piece of working code at the ready. Thanks alot :)
Fantastic! Looking at pictures of waves just didn't do it for me. This video completely cleared it up. Thank you! Subscribed.
Brilliantly explained from theory to application. Well done!
WOW. Finally I understand the rotary encoder logic. Best explanation I have run into in 10 years. Your description turned on the big light bulb on in my brain and I understand it now. The code is so simple too. THANX!!!!!
your explanations are so clear, makes it easier to understand how this works. thank very much!
well done. thats the best explanation for rotary encoder i ve seen so far
Many thanks for the clear guide on how encoders work, I found the animated graphics particularly useful.
Just plain and simple explanation. Great video, exactly what I was looking for. Thank you so much! 😊
please no stop .. you explain so good
Great Job, articulate and directly to the point. Thank You!
@Samir Ben This is spam
Great tutorial !!! Helps me so much doing my current project. BIG THUMBS UP
Great stuff! I was initially looking at some library to handle this but it’s so easy thanks to your explanation I’ll just handle it myself
You are the Man! Thank you: very clear and very consecutive instructions and video. Great job.
You are my savior in ELECTRONICS.
awesome seeing your videos again its been a long time since you uploaded a video !!
Thanks Mechatronics for your time and work. From Sydney all the best. 👍
Thank you too!
This guy is the greatest.
Very helpful! Thank you so much! :)
This is better than searching for confusing datasheets on the website. THANK YOU A LOT
Glad it was helpful!
Thank you very much !!! Now i understand it :)
Amazing, thank's a lot!
Simple and good explanation
That's What I Want To Know Thanks
great video. simply and to the point explanation
Awesome explaination.. Regards from Indonesia
Very informative! Thanks!
Thanks for the video. Great Job and effort to produce it.
omg you explain so good thanks
Really helpful, thanks.
Great job bro, thanks for everything.
Good explanation, thank you.
Excellent videos, thank you
great explanation! Thanks a lot.
Thank you friend!
Very good explanation
thanks, the best explication!!!
Wow, such elegant code...My overly complex code didn't work well when I spun the encoder quickly, this works flawlessly. Thanks!
It's not that elegant tbh, it should be implemented with hardware comparators and interrupts
@@TheChrisey Agree: the example in the vid is fine
for slow speeds, and when there is feedback, such that if a count is missed, or extra, the user will self-correct, and everything is fine. For higher speeds, you need some hardware and maybe counters, which take care of the counts, and the main software just reads the counter any time it needs the values. Some of the Microchip PIC family have a hardware module built in. A quadrature Decoder. But you can also craft with some of the "soft" progamable gates, e.g. CLB and such.
For very high speeds, e.g. motors at thousands of RPM, you can't really just poll the pins in a loop: you need hardware assist. Or very fast interupts might get you some of the way.
But again: the example is fine for the right kinds of slower stuff.
Also: switch-bounce shaping on the pins can be important, so you only get 1 count per count, not many. I did not look too deep at the code to see if maybe its state always handles that OK enough. A resistor and a cap might be enough, depending on the encoder used.
Grate job.. It was really effective for me.. thx alot and carry on..
Great instructional video
Nice video thank you!
great tutorial thank you.
Great video, short and to the point :)
Glad you enjoyed!
Awesome video, thanks! :)
Thank you. Your code worked. I thought that Kevin Darrah's code using interrupts was working for me but it was not. It was skipping all around but your code works perfectly for me with no skipping at all. How u do dat? Thanks man.
Thanks that was amazing...
Thank you 🙏
So great, thanks!
Dear Friend, pls, upload another ligh & simply tutorial like this, I loved it, Thx You !
Thank you Dejan. You are a good teacher. Go on!
You are the man!
Great video!
Dejan, Great video! thank you. Got it to work. If I turn the dial to quick the nema jump, not smooth and has a pause when reveres. I've tried trimming the drive board and the delay times. Any idea?, thanks again for all you great work.
very nice and short video keep it up 😊👍👍
Huge thanks
Nice video buddy keep it up :)
thanks for your tutorial, it helps,regards
referring your tutorial,so is it possible to synchronize two surface speed of conveying belt/goods ?, since the encoder rotated by a surface speed and give the signal as a control to a motor that can produce similar surface speed to another conveyor for example, thanks for your feedback,regards
GOOD WORK BRO..
Nice info, thanks for sharing with us, well done :)
Can you do a video on measuring the angle of rotation of the stepper if connected the encoder to the shaft of the stepper and if the shaft is rotated manually?
*Thanks! Recommend making a video on controlling position of a continuous servo using a continuous rotary encoder!*
Currently working on such a video. I will publish it next week.
Cheers
Oh, thanks in advance!@@HowToMechatronics
Another recommendation that is likely easy is a record and playback motion robot arm using servos. Bonus points for making it a pick and place machine with OCR!@@HowToMechatronics
Again nice one ! Can you make a separate video on ADXL345?
Great Work
suscribed, videos are very good, I'm studying mechanical engineering, have to choose If I want to specialise in Mechatronics, your videos help me a lot in my choice, very cool
Thanks!
thank you this was very helpful, but you didn't talk about the difference beetwen absolute and incremental encoders..
Nice and clear explanation, thanks for the video. I wonder is it possible to control the LED light intensity using this encoder?
Just use a potentiometer DUH
Such a simple logic to test direction. I finally get it. Thanks so much ^,.'.,^
Thanks!
The best one at yutub ¡
output is different from the code it gives only negative values on CW or CCW direction.
CAN U MAKE A VIDEO WITH IN MENU USING 16x2 LCD DISPLAY ???
Do you know the maximum speed of the decoder? Can it turn up to 200 rounds per minute? I tested once and it was not counting correctly - so the question is - was a problem with Arduino or with the mechanic of the decoder?
Thanks you
thank you
Great explanation, everything i needed to know.
Thanks for uploading the video.
For some modules above program functions only when INPUT_PULLUP is defined for CLK and DT pins
very super and good teching
Thanks!
Nice explanation and animation.
But in your code, it will be more accurate if you use interrupt function to detect the change of signal.
What is the least angle it can move ?
For example
If I connect it to a shaft of a robotic arm will it give 30 counts with 30 degree change ?
excellent
Great work!Thank U!
But 20 pulses for one revolution,how can you show 1,2,3,4,5...n degree ,not 1,9,18 degree?
Hi Dejan, thanks for sharing this helpful tutorial,I would like to use a rotary encoder to replace the menu navigation buttons in my project, your video is very useful.
I notice that you did not appear to implement any software de-bouncing techniques to overcome the switch noise, yet your example did not appear to suffer from switch bounce. Did you use a hardware filter of some sort?
Thanks.
Yeah I was wondering about that. My encoder skips when I move it then when it clicks. So each "notch" counts as TWO. 0... 1,2... 3,4.... 5,6.... I suppose I can code accordingly but, slightly annoying.
Yes, my encoder produces the same behavior.
Maybe the two Serial.print() statements in the loop slow it down sufficiently that the chatter has stopped by the time it looks around again. With a faster arduino like an ESP32 the bouncing may be seen again. Havent tested it but just a thought!
i would like to build a wireless follow focus for cine lens, what's your suggest?
which animation tool did you use?
Thanks
thanks.
Very good
in this example was the encoder connected to 5v at the common pin and then pins A and B were connected to digital pins with pulldown resistors?
Great
If I use a magnetic encoder circuit in micrometal gear motor ...does it be work like stepper motor
Wait for a quick reply
Very good thank you, I love that Black Magic!
thanks
Your code working well but you must put it into interrupt event from rising and falling edge caused by A and B signals.
Can you explain this?
@@MrKadvaga i don't think he can
Very nice
I made something similar using a potentiometer
would you please can you show the circle diagram for stepmotor section, is LCD connection I2C ? thank you
can we use this rotary encoder?
In bidirectional Bluetooth app led brightness controlar project
can you make a video of digital potentiometer x9c103 with and without Arduino? Thanks in advance
nice video
Is it possible to design detent switches along with continous rotary knob? and how if its possible?
2:47 that pitch tho
4:45
how many turns does a rotary encoder have and how would i code it so that when i tuen the knob, it goes to the selected menu and i want to press in to select the menu
If power failure u can get reset to zero or it stay in its value and continue with next
