Generating and uploading BIN files to an ESP8266
When you have a number of cards to flash with the same program, it can be interesting to flash the compiled BIN file directly into the ESP8266. This has two interests. It saves you time on uploading and it protects your source code if you share the program with...
Generating and uploading HEX files to an Arduino
When you have a number of Arduino boards to flash with the same program, it can be interesting to flash the HEX compiled file directly. This has two interests. It saves you time on uploading and it allows third parties to upload a program without using the Arduino...
Using an AC dimmer with ESP32
In home automation, it is interesting to be able to manipulate alternating current in order to control different electrical appliances such as lamps or fans. The AC voltage dimmer is a module allowing to vary the power of an alternating current. It has the same use as...

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...
