In this video, the author will be building a Weigh Scale Controller. It was designed to weigh each wheel of a race car by using 4 load cells making a scale for each wheel. This was so you could balance the weight distribution for better handling. This design uses an ATMega328P and a TPIC6B595 to drive the segments. PNP transistors drive the digits via multiplexing.
