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.

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… ...

If you are interested in building your very own open source long-range remote control transmitter for your next project. You might be interested in a new ...

Both of the freestanding modules (NS73MFM transmitter, Arduino UNO) can be mounted to a breadboard and interconnected. Refer to the hardware setup and proceed. The simple code generates digital tones ...

Once the Arduino is awake, it enables power to the servos via a power MOSFET, then everything’s ready to go; the machine makes its response and goes back to ‘sleep’.

Atmel’s ATA8520D is a transceiver IC for 868MHz Sigfox proprietary networks, intended to be used for IoT and machine-to-machine comms with the Sigfox protocol. It has an RF front end for up and ...

A few years ago Josef Holmner created an awesome Arduino powered wrist worn quadcopter controller that allows pilots to control their flying drones using just one arm, and gestures which trigger ...
