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 transmitter and receiver For the transmitter, he turned an Arduino Pro Micro into a USB sound card which he could plug into his laptop.

Using an EH4104R single zone fire RF receiver with relays and an EH1115EOL single input fire RF transmitter, a wireless link can be easily created for any fire switch with standard contacts.

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 ...

If you’re looking for a simple way to make an RF transmitter, check out [Tomasz]’s Morse code transmitter. His design uses nothing more than a microcontroller and a 16MHz crystal to tra… ...

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 ...

Atmel Corporation has combined an 8-bit AVR flash microcontroller with an RF transmitter in two new devices that target tire pressure monitoring systems.

On transmit the keying mechanism sends pulsed code signals which vary for each letter and thereby stop and start RF oscillations in the antenna according to a pre-arranged sequence. The transmitting ...

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.
