Control several Motors with Raspberry Pi and the MotorHAT

by | 20 Mar 2020 | Tutorials

To control a motor, whether stepping or direct current, with a Raspberry Pi, it is necessary to add an integrated circuit like an H-bridge. To simplify the assemblies, there are shields like for Arduino , called HAT (hat) at Raspberry. We will see how to communicate...
Command a serial controller Maestro with Raspberry Pi

Command a serial controller Maestro with Raspberry Pi

by | 16 Sep 2018 | Tutorials

When dealing with several servomotors and an extra number of outputs is needed to operate your robot (to control Hexana, for instance), a practical solution is to use a serial controller such as the Mini Maestro from Pololu. Prerequisite: Programming on Raspberry Pi,...
Control a DC Motor with Raspberry Pi

Control a DC Motor with Raspberry Pi

by | 4 Sep 2018 | Tutorials

One of the main objectives in robotics is to make things move on their own. To give motion to a robot, electrical motors are oftenly used such as direct current (DC) motors especially for mobile robots. In this tutorial, we will see how to control such a motor using...
