Using a Raspberry Pi Model B +, an affordable motor controller and a common DC motor, The Raspberry Pi guy walks us through the process of controlling a motor, including how to set-up the circuit, how to power it and the Python code you’ll need to control it.
In his latest community video, The Raspberry Pi Guy demonstrates real-world computing using the Raspberry Pi’s GPIO pins. “Because the Raspberry Pi is a low energy device, it lacks the ability to control power-hungry components, like DC motors,” he says.
The Raspberry Pi Guy goes on to explain that you need an external power source, a switching device (like an affordable motor controller) and an everyday DC motor. This tutorial is essentially a ‘Hello, World’ application – the starting point for creating a Raspberry Pi robot.
