The Arduino

About a week ago I bought an Arduino, a single board micro controller as part of my venture into hobby electronics. It is an amazing tool to work with. And it's completely open source! I just have to connect it to the computer using a USB port and upload a program using the IDE freely available on the Arduino website and I'm good to go.

Here's a little demo. I wrote a basic program which plays a melody.

I tried to add in some chords as well but it turns out that the Arduino can only generate one frequency at a time even if you have two speakers. So you can't use it to generate elaborate musical pieces. It works well for old 8-bit music from the legendary 1990s game consoles though.
