![Using two Heltec CubeCell LoRa ESP32 Boards HTCC-AB01 as remote switch as TX and RX
We learn how to use One CubeCell as Sender (TX) and the other as Receiver (RX). We use push button with TX to turn ON/OFF a relay with AC bulb or LED connected to the RX. Step by step code, wiring and demonstration is shown.
