    Play Music With Arduino!

    Hi there,Well... I've never use an Intel Galileo but the most important thing here is the audio library, if there is one for the Galileo board and there is a functional output pin then it would work, I think...The pin is very important, in the Arduino Mega there is only 1 functional pin, the 46, even when almos all the pins are available for PWM, not all of them will work as a speaker, I think this is something that is declared in the library. Give it a try and let me know :)

    Wow! You are doing a great job! And no, haha I'm not mad at all (I already saw your other comment) Great! Yes, Escuchando means listening, if you dont hear anthing it might be the audio files on the SD card, but if you format it as FAT and then upload them again it should work, also check that the output signal is at Pin 46 and also... you might need a bigger amplifier, it will work but a 12 or 24V amplifier works much better.

    Well is really easy, there are plenty of tutorials of how to read a IR remote control with arduino, there is a library for it.Then you only need add some “if” sentences. (This is one way to do it)“If(bla bla bla IR read == Up){ bla bla bla.play(music);}Something like that

    If the program dont detect the RTC module an error will appear in the serial monitorThe same with the SD moduleIf everything is fine then the Serial monitor will show you a “Todo Ok” message and Twinky will say “Mmmmhhh Hola” this its twinky waking up.

    Well thats weird, The sketch its the exact same that I upload into my Twinky, those lines of pinMode declaration are not essential buy you can try, but now that I remember.. I made a few codelines for comments of errors, If you open the serial monitor while running the Twinky_2 what does it tells you? You can use this tool to see the step that the program is into it.If there is a trouble with the RTC the program simply wont start at all.Also, if you can send me some pictures of your connections culd be usefull I really think that the problem will be in another module

I hope.

    Oh my... I am really really sorry, I mada a HUGE mistake on that schema... I am checking the code of the ARDUINO and the motor and the microphones are wrong...The correct connection will beA0 for one MicA1 for the other oneand A4 & A5 are the outputs for the motor... Again I'm really sorry to cause you that much trouble...You can fix it by code or you can fix it by hardware.I think that if you have everything on the Mega Shield the easiest way eill be the code,You only need to chenge a few lines in the main loop like so...void loop() { digitalWrite(R,HIGH); digitalWrite(G,HIGH); digitalWrite(B,HIGH); nexLoop(nex_listen_list); if(digitalRead(A4)==HIGH){ //A1 IS THE INPUT PIN FOR THE LEFT MICROPHONE Izquierdo(); } if(digitalRead(A5)==HIGH){ //A0 IS THE OUTPUT FOR THE...

    Resuming the changes will be at lines:61 and 62, Change the M1 and M2 Values247 and 248 change the inputs to A4 and A5292 and 294 change the if sentence with A4 and A5 instead of A0 and A1, I can make this changes if you want to, and then upload it to the drive, of ir you are going to make the changes by hardware then just neet to switch the cables (if you still can do it) and leave the software like it is right now.Let me know

    Also... dont forget to use an external 5V supply, the 5V output from the arduino wont be enough to move the motor

    Hi there, ok yes, I use the Arduino UNO schema only to show how to connect the L293D, the outpus signals from the mega are A0 and A1, so... connect everuthing like the UNO schema (Vcc,Gnd and Motor Outputs) but the signals from the Mega to the motor to A0 and A1 instead of 10 and 11. I hope I've being clear...Anyway I think that the problem will be at the L293D, be sure to connect it like this, with al Vcc's and Gnd's

    Hi!Well, the software is really simple to use, you only have to record your commands and assing them the pins to activate, the main process it is running on the “ShpeakUp Click”, you dont need to do much just connect it and it will start after a few seconds

    Hi there, I'm sorry, I haven't been around lately, but this car application is one of my plans tooThat's a good idea, the random generation MAC like the one that apple use on the WiFi connction. Maybe that could be the answer, Using WiFi... But I havent work that much with WiFi, BLE would be a suitable option at the moment, I'll work in this project and I'll keep in touch with you, have you already done it?

    The way to connect the SD should be:MISO - 50MOSI - 51SCK - 52CS/SS - 53And I belive that you can connect it only to 5V and the PCB has a voltage regulator, the SD cards work with 3V3Aaaand you are totally right, the resistance should go between Data and VCC, to increase the signal, but this worked only when I had the circuit on a protoboard, when I made the shield I toke it away

    Great! I know... the waiting can be really long with those suppliers, waiting is the price to pay for lower prices hahaYes maybe is not the same motor but I'm glad it worked, have you tried to add some grease to the Base? I did that to help the motor and reduce the current consumptionI'll be aware of your messages,regards!

    La Raspberry era una de mis opciones porque quería agregarle algunas funciones de Machine Vision pero ya hay otras tarjetas como la Open MV que tiene funciones muy buenas y pudiera reemplazar el arduino mega por un ESP32, hay incluso otras tarjetas que tienen integrado Alexa de Amazon entonces hay muchas opciones, para qué agregarías exactamente con la Raspberry? La pantalla que es de la marca ITEAD tiene su propio software para diseñar la interfaz y es muy facil de usar, puedes buscar algunos videos en youtube

    Si! Puedes guardar frases de varios segundos pero entre más tiempo, mas margen de error generas

    NICE!! I'm really happy!I had a trouble with the printing of the body too, almost at the beginning, but I was able to restar the printing at the same point, and also have trouble with the SD card but it is mostly because it is not compatible with all brands, I used a diferent one and then it worked,Thank you again for making a Twinky, keep me up with the advances!

    Hi there!The base took a really long time but not that much, maybe you can change the infill rate to 5% or so, I made a test and with ABS 1.75mm, 0.2mm layerheight and 5% infill would take about 36 hours.The head (Cabeza) doesn't need any support.

    haha no, not at all, thank you for the sugestion, AliExpress takes about 2 months to bring me anthing to México :s But already found it in adafruit and dfrobot, it will be on my next shopping cart, I'll let you know if I made something interesting with it and Twinky

    1. Right! I totaly forgot the microphones pins on the schematic! Sorry, they are connected to A0 and A1.2. I added some comments to the Arduino Sketch, you should be able to download it now with the updates, there you can see the declarations of the SpeakUp input pins(The good ones... haha)You are right...My mistake! haha again... the schematic is wrong, I will change itThe M1 and M2 variables are for the motor only. you can change this pins if suited you, all depends of where you place all the modules on the shield, just dont forget to change it in the sketchSorry for the mistakes and thank you for the questions, you are helping me me to improve the instructable.

Yes, or you can use 3 LEDs instead, I'm not using analog write for them so the 3 colors ar connected to digital outputs, you can improve this using the PWM outputs of the arduino Mega and make a lot of different colors, this is optional.13. Yes an Arduino mega shield, the Capacitors are just connected between 5V and GND there is not much reason to use them, I wasn't planing to make my own power supply but with the ones of the PW supply should be enough. The resistor (I think it was 470ohm) is connected between the output signal of the DTH and VCC but I ended up disconnecting it because it gave me problems to read the signal, in my protoboard worked fine but once soldered the arduino sended an DTH error message sometimes. Try it with the resistor first.14. DTH1115. I'll attach an imageDont forget about the L239D motor controller, the current of the arduino output is not enugh to move the whole body, it is really easy to connect, since is just one motor you only need to connect one side.I didn't add a pictire but you need a 12V transformer or any other 12AC source mine is 12V 1.5AThe SpeakUp click has Tx and Rx pins also SPI comm but I couldnt find information about it, so the easiest way to do it is with parallel from IO1 to IO6

    Sure, that could be an option, I knew about it but I've never used one before.Maybe for another project like this, but the truth is that I feel really comfortable with Arduino and their platform.One of my initial toughts was make it functional without the internet connection and thats what I made but yes! could be an interesting way to improve it.I’ll search more about it,thanks for you comment!

    You are talking about the schematic right? This is a reference picture of how you should connect every module. I know, it is a bit too simple but I think you'll get the idea about the 8 Pin conncetor representing the arduino IO pins.Also... the pin numbers of the shcematic are wrong, I made it in about 15 min so I didn't change this labels but if you ignore them and just connect them like if you where on the top vew, it should work.Try to add one module at the time, test it, and then add the next, that worked for me, and you will be less frustrated finding whats wrong if something is not working.

    Thank you for your comment! And you are absolutely right! Use one old Laptop it was one of my original ideas, in order to add some image processing and some harder tasks.My electronics engeneering friends always are making jokes because I always use Open Source products and over all the Arduino, but as you said, I'm trying to show what you can do using just an Arduino as the main processor. And I will add more to this project, the memory of the Arduino is at 48%, I wonder what can I do with the other 52%...

    Wow! You have some design there! I could use some of that too, I really like the movement of the head.But I have to tell you, 3D printing it wasn't my first option I wanted it to make it fluffy like a teddy bear or something and make it dance...But maybe in the next version.

    Thank you, I'm glad you like it!

    I updated the instructable, adding an other step with a simple schematic.Tell me if you have any other questions!

    That could be an option but... what would you use the arduino for? Maybe I can add the bluetooth and control the music commands from there (Play, Stop, Next... ), but I wouldnt send the audio from my phone, for this you can use basicly any bluetooth audio module.
