= 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 [http://www.arduino.cc/ Arduino Uno hardware] to build a basic lap counter.  This hardware is very popular and well supported by the community.  The [http://www.flipsideracing.org/ 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.
