Move clearIrc() into for loop

- Sometimes the haptic motor driver will throw a fault when increasing the applied power so we will clear the flag using the clearIrc() in the for loop as opposed to waiting to exit the for loop and clearing the flag
- adjust Artemis pin definition from PWM0 to a pin value (i.e. pin 2)
- add debugging output for the applied power to be consistent
- adjust defaults to Artemis as opposed to Teensy
