How 433 MHz RF Module Works & Interfacing with Arduino

In this video, we will be learning about the 433MHz RF Wireless Transmitter and Receiver Modules. We will also learn how this module works and how wireless communication occurs between them using Amplitude Shift Keying (ASK) Technique.

Finally, we will learn how to use this module with Arduino to transmit and receive data packet wirelessly. And best of all, these modules are super tiny, allowing you to incorporate a wireless interface into almost any project. The transmission range can be increased by increasing antenna length. The antenna length should be 69 cm but such a long antenna is not feasible. So a 17cm antenna can be used.
