Using an AC Dimmer with ESP8266
The AC voltage variator is a module that allows to vary the power of an alternating current. It has the same use as a transistor in direct current. It can be used to vary the brightness of a lamp supplied with 220V or to vary the speed of a fan, for example. We will...
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:...
Communication between two ESP8266 via WiFi
The NodeMCU ESP8266 is a small microcontroller with a Wifi chip. It is possible to establish a communication between two ESP8266, when they are connected on the same network. In this tutorial, we will see a Master/Slave architecture, in which an ESP8266 will play the...

Programming an ESP32 NodeMCU with the Arduino IDE
ESP32 NodeMCUs are more and more used to make connected objects thanks to their embedded Wifi and Bluetooth links and their computing power. We will see how to use the Arduino IDE to program a NodeMCU. The way to configure the Arduino IDE is similar between these...
Using an AC Light Dimmer with Arduino
The AC light dimmer is a module that allows to vary the power of an alternating current. It has the same use as a transistor in direct current. It can be used to vary the brightness of a lamp supplied with 220V or to vary the speed of a fan, for example. Material...
Using a ServoHat with Raspberry Pi
The ServoHat is a shield for Raspberry Pi that is based on the PCA9685 controller. The PCA9685 module is a 16 channel controller that allows you to drive 16 PWM outputs via I2C communication. It allows among other things to free inputs and outputs of your...Products
