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 ...

This project documents the design and implementation of a low-cost infrared (IR) transmitter and receiver system suitable for industrial wireless communication. Developed using off-the-shelf ...

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 ...

ESP8266 Modules: Enable wireless communication between the transmitter and receiver. Arduino: Processes joystick inputs and sends commands to the ESP8266 for motor and servo control. L298N Motor ...
