So I'm a software guy by trade, but I took some electrical and computer engineering in college and enjoyed the basic breadboard and circuit logic stuff. Recently I discovered Arduino, which is an open-platform microcontroller system for creating home electronics projects. It's basically a tiny computer on a board with a bunch of different input and output pins that you can program with a C-like language on your PC. You send the program across USB to the controller and wire it into real electronics components to make home projects. You can start with simple things like making the LEDs blink in repeating patterns and move up to all kinds of fun projects with knobs, noise, sensors and what have you.
So, is anyone else into home electronics projects? What kinds of stuff have you built or want to build? Have any favorite beginner kits or books? Any clubs or groups you work with?
