I'm slowly working on my first electronics project. I decided to go big though and I now have 200 RGB LED modules (from 5 strings of GE15 Christmas lights) hot glued into a 20x10 matrix. I'm still nervous about blowing something out though, so I'm hesitant to wire up the power. Eventually it will be a connected to a Arduino Uno with an Ethernet shield. :-) Fun hands-on project for this software guy.
