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 ...

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 ...

The FM receiver module is based on the TEA5767 [1, 2] chip. It is a well-known module that could be controlled via the I2C bus. It covers the FM frequency range from 76MHz to 108MHz. At the output, it ...

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 ...
