Quick Question

[Zsuttle]

Good, I finally get to help someone

The diode is to limit any inductive kickback from the motor as it winds down. Effectively, it prevents overvoltage from the motor as it attempts to keep the current going.

The capacitor is to smooth any voltage fluctuations present in the circuit. For the circuit to work, the capacitor should be unpolarised and shunted with the diode, across the motor. (A film cap will do)

Hope this helps,
Zach

It does! I kind of figured the diode's purpose (after I thought about it for a bit). Thanks for the help.
