I am not a big fan of programming. I may like it, but I try to keep it down to a 555 timer, like in this ible. However, when it comes to synthesizers, I kinda NEED programming. One day, while exploring Synthesizers, I came across something known as chiptunes.
I decided to listen and found the music really awesome. So I tried to make it with Arduino. Didn't work. The code was not in the Arduino language. Some browsing of the internet forums led me to find that an Arduino forum user by the name of Stimmer had ported Linus Åkesson's Hardware Chiptune Project to the Arduino.
And now, here is that project.
You will gain:
A machine capable of playing a tune every time you push a button to activate it.
You will lose: (Materials)
A speaker+possibly an amp
2 jumper wires (If your speaker doesn't already have them)
