Control several Motors with Raspberry Pi and the MotorHAT

Control several Motors with Raspberry Pi and the MotorHAT

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...
Power measurement with Arduino and INA219

Power measurement with Arduino and INA219

The INA219 Sensor is a current and voltage sensor for easy measurement of power. In some applications, it is interesting to measure the electrical power exchanged between devices. For example, measuring the power recovered by a solar panel. We will see in this...
Control your project using an IR remote

Control your project using an IR remote

There are different ways to communicate with a system. One of the most used, especially with television, is the infrared remote control. We will see how to drive an Arduino using a receiver and an IR remote control. In this tutorial, we use an IR remote control...
Modulate the color with the RGB LED

Modulate the color with the RGB LED

The RGB LED provides a wide range of colors. It is composed of three mini LEDs, red, green and blue (hence their name RGB); close enough for their lights to mix. Therefore, it is piloted in the same way as three independent LEDs. For instance, it can be used to create...
Control several motors with Motor Shield V2 and Arduino

Control several motors with Motor Shield V2 and Arduino

The Motor Shield V2 is an expansion board for microcontrollers Arduino UNO and Mega to control DC and stepper motors. For motor control, it is possible to use integrated circuits directly but their use requires significant wiring can quickly become unmanageable. To...
