Most often ultrasonic transducers are used for distance measurements, and in the DIY world, usually as a way for robots to detect obstacles. But for a weekend project, [Vinod.S] took the ultrasonic ...

Want to know how to interface an Arduino with a Radio Control Transmitter? Read on to see how. Signals from the Arduino can be sent to the transmitter as a result of this interface. The arduino signal ...

Packed with an incredible amount of hardware, and increasingly likely to be running an open source firmware, the modern RC transmitter is effectively a little multi-purpose computer in its own right.

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 ...
