Here's an example code for using a relay module with WiFi control using an ESP8266 (or ESP32) board. This code will allow you to control a relay via a web interface over WiFi.

The WiFi Link firmware is an Arduino sketch so you can build it in Arduino IDE and upload it to ESP from Arduino IDE. Building WiFi Link firmware from source files gives you possibility to build the ...

Jolly ESP8285 + ATMega328PB WiFi module for Arduino UNO replaces Microchip ATMega328P MCU with a DIP module.

A 26.000MHz crystal is used in the ESP-01/ESP-01S module. In order to use the ESP-01 Wi-Fi relay module, a programmer/programming adapter is required to program the ESP-01 module (see below). Also it ...

Despite a wealth of tutorials for setting up and writing code for the ESP8266 WiFi module, there has not been much of anything on programming this cheap wireless module with the Arduino IDE ...

Someone has invented a way to add Wi-Fi to a standard Arduino Uno, by proposing a module that drops into the DIL socket normally reserved for the ATmega328 – it will not work with Unos that have a ...

If you enjoy building and designing Arduino systems and devices you are sure to be interested in a new tiny Wi-Fi Arduino development board called the Spark Core.

It can be used to add Wi-Fi design elements to Arduino designs, while offloading the burden of TCP/IP stack and networking applications to the included xPico Wi-Fi module. The xPico Wi-Fi device has a ...

It’s a WiFi module packaged in the familiar Arduino shield form factor, and costs $55 USD. For the hardcore hackers out there, you could always get a bare Microchip WiFi module and get it to ...
