Thanks for the video.
Small improvement.
To avoid parasitic noise at the start I add a sequence "0, 6, 14, 22, 30, 38, 46, 54, 60, 68, 74, 82, 90, 98, 106, 114, 122," at the start of "const unsigned char sample0 [] PROGMEM".
As a precaution, perhaps it is better to attack the transistor with a 150 Ohms connected to the base.
Thank you for this tutorial. Looks easyer than I thought.
Nice project and good inspiration. Also thank you a lot for the files, I was just looking to download the apps until I read your description and downloaded them from there. Keep up the good work
Can you share those files, please... I couldn't get it.
Glad I could help
@@ElectronicsBd Can you share those files again, please??? I couldn't find.
This is awesome! Thanks for the video!
its good, I tried and it worked the way your showed.. Thanks for the code and the files, thats a cool job. Only thing about this project, is that it takes away 82% of the board space, otherwise cool one.
Have you found any way to include multiple sounds? And the reduction of memory utilization. I am trying to do it. If you can help it would be great.
Any chance you could share the files? The link appears to be dead. TIA
Thank you from Algeria you are the best
Welcome 🤗
Tx Ahmed and Roland Jolivet, now I know how to do this. I just got this idea today to make a countdown timer for a girl with cerebral palsy that can not speak, however you can use a technique called voice cloning to synthesize a similar sounding voice based on her utterances, that is the sound she can still make. And so when that works I put it all on a microcontroller with sound samples from "Ten" to "Zero" and then she will have her own countdown timer with her own voice to for example 🔥 🚀 Or just listen to herself speaking.
Thank you so much for details ... 👍
Really helpful, thank!
Glad it was helpful!
Nice video! Thank you for sharing your knowledge.
Welcome, Glad it helped
NOOO! I had two speakers like that years ago and now I have no idea what happened to them. Oh well, I have two more but much bigger and they're a little to good to goof around with if "bad luck" strikes haha!
No matter what ... great video! :D
Thank you for this video😊
My pleasure 😊
Amazing tutorial, thank you! could I ask a question? there is a way for an outside button/trigger instead of that on the motherboard? for example in a BLASTER, this will perfect to get the sound clicking the trigger, the only problem is that in your video I can see some LAG from the trigger to the sound, maybe a lightweight sound will be more rapid.
doc1429 thank you 😊, I’ll try it
Ya; just connect it with a PIR motion sensor
Thanks for the video
Can you make audio plays on car’s speakers whenever you startup engine?
i did not knew electronics bd had a channel, i bought many things from them
Thanks for staying with us
@@ElectronicsBd @ElectronicsBd Can you share those files again, please??? I couldn't find.
thank you very much!
4:58 this is what I came for. Thanx a lot!
Glad, It helped.
@@ElectronicsBd bro can you please tell me the name of this application please
or can you send me the link
@@ramshripandi9473 it's available in the link he provided
@@vonshirco7473 the link doesnt work
Thank you so much, the video is really helpful. I just have one questions , when I tried it, it played only the first second only not all the audio how can I fix it to stay longer
You can ran more lengthy audio, if you add an SD card.
It works 👍🏼
Good to hear
This is very helpful video because I am making a robot and not knowing how to make amplifier thanks 😎🥰
Glad it was helpful!
@@ElectronicsBd Yes can we use this amplifier for talkie library
@@TechNerdPrash I don't know much about talkie library, you have to try dear.
@@ElectronicsBd Thanks
@@TechNerdPrash Welcome
Nice video and good explanation but i can't open the audio encoder do you know what to do?
Wow, it looks so easy. Can we save the voice in this arduino and get another power supply for activate the arduino and the speaker? How much the voltage ?
it think 5 volts
Arduino nano can be powered by 12v max using the raw pin
Heyy really nice vid but where do i find the encode audio software and where can i download it????
I got a couple of speakers from a broken radio and they work!
Holy volume instability! Was someone playing with the sound knob during production?
Thanks for the video!
Do you have data of the speaker? Which speakers are suitable for the Arduino?
thanks in advise, manu
Could I drive the speaker from the 3v3 pin and what adjustments would i need to make
This saved me during midterms
@Fabian Leopold your comment has me in stitches
Congratulations

@ElectronicsBd Can you share those files again, please??? I couldn't find.
What is the max audio file size you can upload it to the arduino?
Helpful tutorial
Glad to hear that
Can we connect it to different ports like to d4 instead of d11 and to any other than 5v port
Hello, I have been following this video an I've noticed the Encode Audio app you have , I've been searching an I can't seem to locate it.
can you please tell me where I can find it or one like it that I can use .
Hi there i am looking to do add this to my RC Plane project, but I don't want it to be connected to the laptop. Would it be possible to power this through a battery? Help would be appreciated. Thanks
Hey! Nice video!
The link to the files is not working anymore. Could you send me the files?
Thanks :)
Simple but nice video , that audio ecoder app is pretty cool. Is it possible to use it and get perhaps 16 bit output instead of the 8 bit ? Im planning to use an esp32 pwm with perhaps 10 or 12 bit resolution with a simple r/c circuit or DAC chip
Wht typa software he use to convert the audio to code
Its really nice, but is it possible so it can play only when, for example a correct coin is inserted into a coin acceptor? i would want to learn the code from it 😊
add a motion sensor so that it sees when the coin passes, and then use "if then"
May i ask a question?, in my compile is error, it said avr/interrupt.h no such file or directory, may you can help me with that problem
Damn music is irritating
we won't use such music again
Yeah, I though it was terrible too. Worse than advertising music.
@@pow9606 We use batter musics now.
just watch our recent videos.

How many seconds of audio can we fit into a stock arduino nano?? nice tutorial thank you!!
I depends on the file size, I recommend you use an SD card with arduino.
@@ElectronicsBd can we interface external eeprom and put files there
wow,how did yoy download encoding softwear ?
will it still work without the bc547 transistor?
Wow its nice project thank you but i have a question can we use wemos D1 R2 or NODMCU ESP8266 micro controller instead of Arduino nano?
yes
Thank you
@@elisabethandarge1194you're welcome.
but what speaker do you use? how would i use a speaker without amp transistor?
Just wondering can you use something else as a substitution for BC547? or like would it be okay to use op amp for a substitution. Is BC547 working as an amplifier ?
yes, BC547 is working as an amplifier.
You can add your own Amplifier circuit if you want,.
@@ElectronicsBdIn Greece, the only amplifier I can find is the BC547B, will it work the same?
I just did this project with a 2N2222A transistor and it worked fine.
first thanks for this project but it work as a repeating message only the flame neither detect nor not the message is playing can you edit the part to make the flame detect then the message play?
Super Thanks
Thank you too!
"attention please, fiya in the building"
Please, how can I program that the sound doesn't show up until the second click?
Why it is necessary to connect + to D11? It works on 11 but doesn't on other PWM inputs
yeah, it works on other PWM pins
Thx
Any time
Nice! but how do i lower the volume tho?
Why is the text microscopic?
Equalizing the sound volume with music volume is nice too.
how much program memory does this code use? there were nine words. Please reply ASAP. great video, thanx.
I can't use your library, is it normal? My arduino says that it did not find the library please help me I need help. I'm desperate I finally found the perfect tuto but I can't use it !!
Can i do this on a teensy LC?
It doesnt work on my arduino mega. i can play simple tones, but if i upload the example "playback". nothing comes out of the speaker.
From where did you find the speaker, plz provide the link.....
Every BJT NPN transistor NEED a resistor bevor the base! Realy! Or it will destroy the transistor shortly. use a 470R resistor. The loudspeeker is inductive. You need a 1n4148 parallel to the loudspeaker, pointing the ring to positive.
yes,
Thank you for your concern dear
I don't understand what Jen's is saying. Need a 470 resistor before the transistor where? No clue what the last sentence means either. First time attempting audio with an Arduino so trying to learn all I can
@@zero2583 He's saying to add a 470 Ohm resistor to the base pin of the transistor.
Which software you used for encoding link please
Where do you specify in the code the port you attached the speaker to?
PCM documentation say pin 11
Is there away to make it play when powered up?
Can u make one tutorial for microbit
Can you program led light to It and find different audio files I plan on making a dashboard figurine of bumble the abominable snowman from Rudolph the red nosed reindeer
Can you tell me how can do this instead of button and use it with ultrasonic sensor
Hi, can I know the specifications to the speakers please?
Hello, the speaker is a 4ohm speaker.
thanks
You're welcome!
what is the less memory way it uses more than %40 of arduino memory
Does it always has to be 8kHz or can it be 16kHz?
where do i download the encode audio??
Thanks
Welcome
Hello. Im trying to get some higher sound because that is not enough so i bought an lm386 audio amplifier module and im connecting the speaker to the output pins, and the 5v arduino to the vcc and the transistor instead of connecting to the gnd speaker pin im connecting to the module's gnd pin, but when i play the sound it makes only some noise. Can you help me? Is there any other way to get some higher sound?
try this amplifier - www.electronics.com.bd/pam8403-super-mini-digital-amplifier-board-2-3w-parts-ic-module-sensor-arduino-transistor-resistor-capacitor-robotics-project-electronics?search=amplifier&description=true&page=5
@@ElectronicsBd Can you share those files again, please??? I couldn't find.
plz tell me how can I change the pin number instead of D11 to Digital 3 on Arduino UNO
how many such commands we can add in memory of arduino so it doesn't exceed the full capacity.
Wow 😂👌
Thanks
Can u pls provide me with the specifications of the speaker
can we put 2 audio at the same time ? i mean 1 for alarm and another one is welcome
Yes
Can this be done without the bread board
Sorry to bother, the files drive is down. Maybe you still have it?
Hello!! I seldom leave commnt but for this, THANK SOOO MUCH!!!. Btw, can I know why need to decrease the frequency to 8Hz?
Its to save on file size.
How do we give our own customized voice alert?
I faced a problem while trying to download the audio encoder. Even if I tried to download java from the java w fix folder, I couldn't get it to work.
Ya did you found how to rectify it because i am also facing the same problem..
can i do this simulation inside the proteus?
cause now not yet have any hardware part
It's your wish
Awesome.
Just what I was looking for.
Quick question if I may, can I connect to the AUX input on a stereo instead of a speaker, to get higher volume?
if you plug it in an amplified speaekr, it will work, otherwise no
Yes you can!
You may shred your speaker depending on the security mechanisms your aux has - check the input voltage and aux/line in impedance. en.wikipedia.org/wiki/Line_level
So definetly NO. (There is a reason why he didn't added the music at the end with the big audio amplifier, because the sound is crap due to the 8k sampling rate.
This project is a "playing with a speaker" project. This is what you are looking for: www.pjrc.com/store/teensy3_audio.html
and not too expensive.
yes.
studio.czcams.com/users/videoBPR6nsGQ1Mc/edit/basic
@@ElectronicsBd You mean this link :) czcams.com/video/BPR6nsGQ1Mc/video.html The voltage input signal is still too high, if you watch your audio curve diagram you will see what I mean. When the aux input voltage is too high for the input your stereo system cuts off the edges but not every system might has this protection.
Can you make this with ultrasonic sensor please
hey, while playing the file can the arduino do other code?
its a byte array? i can do a software by my self. that convert wav to bytearray and send to arduino is possible? this cause i cant download encodeaudio i have mac...
Hey, did you found a solution? I'm searching this too.
where to download Encode Audio software?
Plz give me the link of audio encoder
connected to piezo speaker, sound output more quiter....any suggestion sir help? ^_^
which encoding is this? mp3 to ?
How did it work without defining Pin number in code?. It isnt working on my arduino UNO
Can I connect 8 ohm speaker with this configuration and will the same transistor be enough for amplification? I am concerned because I don't want my circuit to be damaged.
been 8 months but I'm using it just fine although I am using a different transistor
I compress my audio (2 second clip) down to 4kb and still when i tried to upload the sketch it takes up too much memory. Any tips?
Try to store it in arduino's flash memory
PROGMEM atrribute in variable declaration
can the same method be used for nodemcu8266
Please use this system with ultrasonic sensor as a security system
Coolll... !!!
Thanks
Would it be possible to configure the sound to loop as the button is pressed, and end when it's released?
yes
You could split the audio sample array into many smaller arrays and then have a loop play each smaller sample while you hold down the button :D
@@BenStoneking can you show me code?
Please respond to this, but how could i play sound files from my pc on that
