Using the EEPROM with the ESP8266
The EEPROM is an internal memory of the ESP8266 microcontroller which allows to keep in memory data after restarting the card. When working with microcontrollers, it is interesting to keep in memory data such as the identifier and the password of the Wifi. Material...
Using the EEPROM with the ESP32
The EEPROM is an internal memory of the ESP32 microcontroller that allows to keep in memory data after restarting the board. When working with microcontrollers, it is interesting to keep data in memory especially when the card turns off whether it is wanted or not, as...
Using an RFID module with an ESP8266
The RC522 RFID module is a smart card reader which, among other things, allows to activate a mechanism when the right card is presented to the reader. In this tutorial, we will see the management of an RC522 RFID module with a NodeMCU ESP8266 card. Prerequisite:...

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...
