Here's a video on one of my new favorite parts - the MCP7940N RTC (Real Time Clock) because it provides a super cheap way to add time keeping to your projects. I've been using this part for a while now, but just now got around to making a video on it. Stay tuned for videos showing how you can use the alarm outputs to wake up from low power sleep states on the Arduino. Also, accuracy testing stuff will be coming soon as well...

Here's the wiki for the RTC board: http://www.kevindarrah.com/wiki/index...
