Tom's October Blog

The aim this month was to understand more about how the microcontroller functions are used and how to connect and power the motors on the board.

The first step was to work out how to attach the motors to the main board; each motor has five connection that need to plug into the microcontroller. Two wires, both blue, are the motors power source and connect to port F. The other three power and control the tachometer, which allows us to get feedback on how fast the motor is actually traveling. The red and black power this, the red carries a 3.3v current and can connect to any port supplying that power, the black is the ground and connects to any 0v pin. The yellow wire is the feedback from the tachometer and connects to pin 5 or 8. The board itself also needs to be powered and they are connected to BAT A and BAT B. The layout is below.
