DeskCycle Speedometer

This project uses an Arduino to act as a speedometer for the DeskCycle (www.deskcycle.com), the same code can be used for anything that has a trigger when a wheel revolution completes.

Currently the Arduino monitors pin 7 and measures the time between revolutions to calculate RPM and Speed. The client application requests data by writing the following chars to the serial port;

  • h (handshake) - Arduino returns "DeskCycle Speedo", enables the client to search COM ports for the speedo
  • s (speed) - returns the speed in MPH
  • c (cadence) - returns the RPM of the pedals
  • b (both) - returns "speed,cadence"
