This series of projects explore concepts of radio communications. We use LEDs to generate (very high frequency) radio waves and photo-resistors to take the place of radio antennas. These ideas are ...

Long range wireless control of a project is always a challenge. [Mike] and his team were looking to extend the range of their current RC setup for a UAV project, and decided on a pair of Arduino ...

Light fidelity (Li-Fi) is a widely adopted form of wireless communication that uses optical energy to verify device ...

I recently searched for a digital FM transmitter kit, but most of the ones that I found online were either too expensive or did not have enough flexibility for my future applications. So I decided to ...

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 ...

How are we going to transmit our signal? Feeling ambitious, we decided to go wireless. We may not to able to make a mobile phone system but our very own radio station with a transmitter and receiver ...
