IoT Project: Use NodeMCU or D1 Mini to control DC Motor over WiFi with Relay

Using this Arduino code we can control a DC motor 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
