Welcome to the Flip Side Dio Development Site

The Flip Side Dio project is a DIY project for people that want to make a simple lap counter. In the past people would use the parallel port to build simple lap counters with cheap hardware but modern computers no longer have a parallel port. For our project we will use the  Arduino Uno hardware to build a basic lap counter. This hardware is very popular and well supported by the community. The  Flip Side Racing Software has built in support for the Dio hardware. An Arduino sketch is provided that can be uploaded to the Arduino Uno.
