Controlling 8 relays with ESP32 and shift register

Controlling 8 relays with ESP32 and shift register

In this series of tutorials, we will see how to drive a multitude of relays with a NodeMCU32S microcontroller and 74HC595 shift registers. We will then see how to address each relay individually. Finally, we will create a web interface to control each relay via the...
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...
