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 ...

Remote control allows the location of the control point (typically the main studio) away from the transmitter site. The rules state that “The remote control system must provide sufficient transmission ...

We may not to able to make a mobile phone system but our very own radio station with a transmitter and receiver might just be possible. What is a transmitter? Radio can be incredibly simple.

These days, 433-MHz RF transmitter/receiver modules are very popular with electronics hobbyists and tinkerers. These cheap short-range radio modules can be used with almost all microcontrollers for a ...

Why does a spark produce radio waves? Air normally does not conduct electricity. However, if the voltage is high enough (for a given amount of air) the electrical energy causes the air atoms and ...

Researchers have developed a tiny unit that is both an optical transmitter and a receiver. Researchers at Linköping University, together with colleagues in China, have developed a tiny unit that ...

The UGreen Bluetooth 5.0 Transmitter and Receiver solves that conundrum by making our wireless headphones compatible with such outdated technologies.
