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 ...

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 ...

The transmitter/receiver pair operates at a frequency of 434MHz. An RF transmitter receives serial data and transmits it wirelessly through RF through its antenna connected at pin 4. The transmission ...

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 ...
