I have the following:
- Arduino Uno and/or Duemilanove;
- DC motor salvaged from pound shop toy; and
- a 9v battery.
What are the missing components to drive the motor, in a single direction, with a ON/OFF only functionality? I should probably account for PWM in the future, but always one direction only.
From my very quick investigation probably just a MOSFET and a Zener Diode will be required, but I'm not sure. Oh, and a capacitor to isolate the circuitry wouldn't harm, right?
