The virtuabotixrtc.h arduino library is a testament to the power of open-source hardware. It takes a potentially complex task—bit-banging a 3-wire serial protocol—and turns it into three lines of code. For beginners building their first digital clock, greenhouse timer, or automated feeder, this library is a perfect starting point.
