Configure an ESP8266 as a Wi-Fi Access Point

The esp8266 microcontroller can be configured as an access point (AP) and generate its own wifi network with ssid and password. This method is useful when you do not have access to a wifi network or if you want to work on a network specific to the microcontroller....
Communication between two ESP8266s via UDP

Communication between two ESP8266s via UDP

The NodeMCU ESP8266 is a small microcontroller with a Wifi chip. It is possible to establish a communication between two ESP8266, when they use the same network. In this tutorial, we will see an architecture with two NodeMCUs that will exchange data via the UDP...
Using the ESP12E Motor Shield

Using the ESP12E Motor Shield

The ESP12E Motor Shield is an expansion board that allows an Amica ESP8266 NodeMCU (V2) to drive two DC motors or one stepper motor. We have seen how to drive a DC motor using an H-bridge which can require a lot of wiring when using the simple IC. For an embedded...
Generating and uploading BIN files to an ESP8266

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...
Using an AC Dimmer with ESP8266

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...
