Arduino and the legacy printer port.
Try at your own risk!!!! It could brick your arduino!! 1. Minimal Arduino I recently got really interested in Arduino hardware. For those who don't know what it is, Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments. http://arduino.cc/ So I looked for ways to make my own board but as I am not into electronics, I needed something really simple, where I just needed to put in components, abracadabra and it should start working. So after much research (Googling actually) I have now learned how to make a minimal Arduino clone.
