Old infrared remote controls can be a great way to interface with your projects. One of [AnalysIR’s] latest blog posts goes over the simplest way to create an Arduino based IR receiver, makin… ...

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 ...

In my case I have used only 3 x 330Ω resistors, 3 leds and a TSOP4838 IR receiver module. You must check the datasheet before use the IR module to see which pins connect to the power supply and which ...

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 ...

Step 2: Set up Arduino with 433Mhz transimitter and receiver This link has a pretty explanation about datasheet about transmitter, and this one for receiver. After you read through the datasheets, you ...

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 ...

Infrared headphones can be used for listening to music or television cordlessly. The headphones utilize a transmitter that connects with audio cables to the audio source, such as a home entertainment ...
