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 ...

Overview Hydrosmart is an advanced water level monitoring system that leverages wireless communication, a touchscreen interface, and real-time data visualization to control and monitor water levels ...

The robustness and relative insensitivity to misalignments and mismatches make the LCC topology popular in wireless power transfer (WPT) applications, including more challenging dynamic or ...
