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 ...

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 ...

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

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 ...

Send high-resolution video and audio signals at distances up to 1000' with this Fletch Fiber Transmitter & Receiver Modules Kit for HDMI from Kondor Blue.

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 ...

Smaller transistors made chips faster, cheaper, and more capable. As Moore's law slows, a different limit has come into focus ...

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.

The receiver module uses the same type of IR module found in the cable box to decode the signals from the remote.
