ESP32 Socket Server: Controlling a relay remotely

In this tutorial we will check how to control a relay connected to the ESP32 remotely, using sockets. The code will be developed using the Arduino core. The tests of this ESP32 tutorial were performed using a DFRobot’s ESP-WROOM-32 device integrated in a ESP32 FireBeetle board and a DFRobot relay board.
