ESP8266 Project:How to control 4 AC bulb or load using NodeMCU and D1 Mini over WiFi with 4 Relay

Project Video
Project Details

Using this Arduino code we can control 4 AC load such as AC bulb or fan using ESP8266 NodeMCU or D1 Mini over WiFi either from Computer or tablet or mobile phone.

Your Ardino IDE (Arduino Program) must be ready for ESP8266 (NodeMCU or D1 Mini). Else this code will not work. The link to use in the "preferences" of Arduino IDE https://arduino.esp8266.com/stable/package_esp8266com_index.json
