My project status traffic lights

Hi all,

A while ago added an Arduino with some Sparkfun relay control boards to an Ikea childrens traffic light lamp, to use as a software project status indicator, attached to my office build server. They've been working in production for several months now and are a really useful addition to our office. It was my first microcontroller project and was amazed at all the information and resources available to do such things.

Here are a couple of pictures, and you can see more (including a video and all the code) on my blog at



Very nice execution. I know people that have done similar things with PLC's for a heck of a lot more money :slight_smile:
