It is a communication library that allows two Arduino’s to communicate with each other using RF Module i.e. transmitter – receiver pair. This library consists of several functions that are used for ...

1. Description This tutorial shows how to establish a basic RF communication link using cost effective wireless modules (434 MHz transmitter and receiver). The use of low-cost RF modules could be ...

RDM6300 RFID Reader Module The RDM6300 125 kHz EM4100 RFID Card ID Reader Module is designed to read and write data from 125 kHz compatible tags. It can be used in surveillance systems for workplaces ...

For the transmitter, he turned an Arduino Pro Micro into a USB sound card which he could plug into his laptop. That outputs both the audio signal and a 40 kHz carrier signal, implemented using the ...

Use the power amplified NRF24L01 with antenna on the receiving end to achieve a total 1KM of range with the transmitter. Use I2C connector on top of Arduino Pro Mini to give the receiver a display for ...

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.
