Claiming to provide highly stable operation in a 10% smaller package compared to similar devices, the FMRTF3 transmitter and FMRRF1 receiver modules require no external components. They operate on ...

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 ...

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

Cloud2GND's Aurawave AW100 platform employs Ezurio's BL5340PA module integrating Nordic's nRF5340 SoC and nRF21540 RF FEM ...

Targeted for the smart home, this design leverages two PIC MCUs that use a wireless RF transmitter/receiver to control up to six relays and monitor two analog signals.

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 ...

Here’s a surprisly simple way to build yourself a laser-based listening device. It consists of two modules, a transmitter and a receiver. The transmitter is a set of lasers, one is visible red ...
