Why Serial Instead of Wireless? Incompatible USB dongles and receiver modules shipped from Artaflex Little to no documentation using WirelessUSB w/ PSOCEval1 Nearly impossible to debug a wireless transmitter Serial is a simple backup plan

Future Improvements Correct USB dongles and receiver modules now received from Artaflex Implementation of wireless component should only require a few hours work Add Graphical User Interface features
