If we want to implement the project without the library, then we need to change the receiver part of the circuit. VirtualWire.h is a special library for Arduino created by Mike McCauley. It is a ...

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 ...

Wireless sensor node is a sensor node with a wireless transmitter. It has one or more sensing elements with amplifier and signal conditioning circuit or a digital/smart sensor, a microcontroller unit, ...

Old infrared remote controls can be a great way to interface with your projects. One of [AnalysIR’s] latest blog posts goes over the simplest way to create an Arduino based IR receiver, makin… ...

Initially we build a transmitter and receiver to communicate between Arduinos using Morse code sent by pulses of light waves. Next, we consider digital music, which we create by switching a voltage on ...

I found that we could get the radio to reach the length of a 60ft bowling alley, but it worked best with one long range version as the receiver, and a standard module for transmitting.

Designed to accommodate 3-D antennas, the ATA5282 is a LF ASK, 125-kHz receiver with three inputs and a digital 8-bit RSSI output. A complete, hands-free key fob for passive entry go (PEG) systems ...
