  • Brake the motor
  • Change the motor speed slowly

Library Usage:

  • Download the source
  • Place the “ArdoMoto” folder in your Arduino1.0+ “libraries” folder
  • Open example sketch: “file”, “Examples”, “Ardumoto”, “SetSpeed” (or “Braking” or “SlowChange”)
  • Connect the shield (and connect Vcc and GND on the shield to an extra power supply )
  • Compile & upload code
  • The motor should be running as described in the examples
