Drawing an Arduino Circuit Diagram
I've had an Arduino Duemilanove now for a couple of weeks. If you're not familiar with the Arduino , it is " an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software ". It has a small microcontroller, a USB port to connect to your computer for programming, a power socket for providing power when the USB cable isn't connected, and various digital and analog input and output pins, for connecting up to leds, switches and various sensors. It's inexpensive, and there's an open source IDE for programming. Works great, but one issue that I quickly ran into was remembering my circuits. I'd make something up on a breadboard, write a program for it, and then tear it apart to build another circuit. When I wanted to go back to an earlier circuit, I had the program saved, but I couldn't always remember how I had wired up the circuit. So I went looking for a program that would let me document my circuits, and I fo
