This tutorial shows how to establish a basic RF communication link using cost effective wireless modules (434 MHz transmitter and receiver). The use of low-cost RF modules could be practical in ...

This project demonstrates serial communication between two Arduino UNO boards (ARD1 and ARD2). It uses a transmitter module (push button interface) and a receiver module (relay and lamp control system ...

The transmitter project provides 2 channels for transmitting and receiving which operates on the 418MHz frequency. The circuit utilizes a few ordinary components to create the RF transmitter and RF ...

It is often required to switch electrical appliances from a distance without being a direct line of sight between the transmitter and receiver. As you may well know, an RF based wireless remote ...
