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.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
