This cost-effective 433MHz wireless relay switch circuit allows remote relay control using an RF transmitter and receiver module. It is ideal for scenarios where wired connections are impractical or ...

Arduino project for receiving and (in the future) transmitting signals using a 433 MHz RF module. Currently, this repository contains code for a 433 MHz signal receiver, which allows reading signals ...

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 ...

When it comes to giving your projects wireless capabilities, A 433MHz RF Module is the most common and easiest way to get things done. A 433MHz RF module uses the ASK modulation methods to transmit ...

With this circuit, a single transmitter and simple set of user pushbuttons can initiate one of four different outputs, two at each of two remote receivers with very different applications. The ...

//In this Project We will controll 4 relays Remotely with the Help of Radio Frequency (YK04-Rf 315 or 433 Mhz Receiver Module)and its Remote control // Sketch Modified by ...
