In this tutorial we will check how to control a relay remotely using serial communication over Bluetooth Classic. 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. Advertisements
In this ESP32 tutorial, we will check how to remotely control a relay using the Arduino core and the HTTP async web server libraries for the ESP32.
The objective of this post is to explain how to control a relay using the Arduino core, running on a ESP32. The relay board used was this one from Elecrow.
