Connect one of the small DC motors to the "Source" of the FET. Connect the other side of the motor to ground. The high side (Drain) of the FET should be connected to the battery +. The Battery - should be connected to ground. The "Gate" FET should be connected to a PWM pin on your micro controller.

Todo:

  • Make a program to run the following PWM duty cycles: 25%, 50%, and 75%.
  • Make a video of the motor running at each of the above duty cycles (provide youtube link).
  • PWM Frequency is required to be 1.0 kHz (1000 Hz).
  • Show image of oscilloscope showing the different PWM duty cycles and PWM frequency.
  • Provide a SHORT wright up of what you did
  • Show a picture of your test setup
  • Provide a schematic of your test setup
  • Include your Psudo Code example of what you did
  • Include a copy of your source code (in a separate file)
