Description
Throughout this tutorial we’ll be using the FS1000A transmitter and corresponding receiver, but the instructions provided also work with other 433MHz transmitter/receiver modules that work in a similar fashion. These RF modules are very popular among the Arduino tinkerers and are used on a wide variety of applications that require wireless control.
These modules are very cheap and you can use them with any microcontroller, whether it’s an Arduino, ESP8266, or ESP32.
