Wiring

The power wiring diagram is included by way of illustration. We have four main electronic components: the Raspberry Pi 3, our robot's brain; the Arduino Mega; the motor shield; and the servo controller. We will be needing two sets of power – the Pi and servo controller need 5v, while the motor controller needs the full 11 volts from the battery pack. I purchased a 5v power supply to convert the battery to 11v. The motor controller needs power on the screw terminals labeled "EXT_PWR". Hence, we need to create a power harness with two splits – one split that puts 11v into the power supply board and the motor controller. We can then wire 5v from the power supply board to the Pi 3. A second 5v goes to the "servo power" connection on the ...
