Tutorials
Generating Sounds with an Arduino MIDI Interface
In order to generate synthetic sounds on your computer using an interface and create music, it is possible to transform an Arduino into a MIDI device. Material ComputerArduino with USB port Introduction to the MIDI protocol MIDI (Musical Instrument Digital Interface)...
Managing a 4×4 Analog Keyboard with Arduino
Whether it's a calculator or a building keypad, we commonly use numeric keypads. The 4×4 numeric keyboard is a matrix of 16 buttons whose states can be detected by a microcontroller. This module requires only one analog input from the microcontroller unlike the 4×4...
Using the PN532 RFID reader with Arduino
The NFC module PN532 is a smart card reader that, among other things, activates a mechanism when the correct card is presented to the reader. It can be found in smartphones, for example. The RC522 module is certainly the best known RFID module in the Arduino world,...

Control 8 relays using ESP32 and a web interface
In this tutorial, we will create a web interface to control 8 relays individually. This tutorial is a continuation of the project Pilot 8 relays using an ESP32 and the serial monitor. This tutorial can be applied to any microcontroller with a Wifi or Ethernet...
Control 8 relays using ESP32 and serial monitor
In this tutorial we will see how to address each relay individually with a NodeMCU32S microcontroller and 74HC595 shift registers. At the end of this tutorial you will also be able to control each relay using the serial monitor. This tutorial follows on from the...
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...
