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.

The code for the Arduino transmitter and receiver sides is available at their github. Though there is no built-in error correction in the code, they have not had any issues.

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 ...

This was simply an Arduino and a transmitter in the right frequency, loaded up with bit of carefully crafted code.

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 ...

Renesas has announced a 60W wireless induction power receiver IC, compliant with WPC 1.2.4 and compatible with WPC 1.3+. Called P9418, it can also deliver up to 5W as a wireless power transmitter.
