IR Remote Morse Decoder Kit with Arduino Uno — Turn Any IR Remote into a Morse Code Messenger

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Press a button on a TV remote and watch a letter appear on the LCD — you’ve just built your own Morse code decoder that understands infrared light. This kit turns the invisible signals from everyday remotes into a hands-on lesson in communication electronics. You’ll wire up a TSOP1738 IR receiver, program an Arduino to recognize short and long button presses as dots and dashes, and instantly see the decoded character. It’s a clever blend of wireless protocols and classic Morse that makes learning both topics intuitive and fun.

What You'll Build

A standalone Morse code interpreter that uses a standard IR remote as the key. Point the remote at the receiver, tap a sequence of short and long presses, and the Arduino translates the timing into a letter on the 16×2 LCD. The breadboard assembly is clean and portable, powered by a 9V battery, so you can demo it anywhere. By the end, you’ll have a fully working device that explains two core concepts in electronics — how infrared remotes encode data and how timing patterns become human-readable symbols.

What You'll Learn

• How infrared (IR) remotes transmit data using modulated 38 kHz light pulses
• Interfacing the TSOP1738 IR receiver with Arduino to capture button codes
• Writing Arduino logic that measures pulse durations and classifies them as Morse dots or dashes
• Driving an I2C LCD backpack to display letters without complex wiring

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is ideal for school students (CBSE Class 8–10) exploring communication electronics, hobbyists curious about IR protocols, and ATL Tinkering Lab innovators building working demos. It’s also a perfect entry point for B.Tech ECE first-years who need a tangible project to reinforce their coursework. No soldering is required — just plug components into the breadboard, and the AI companion provides copy-paste code and wiring diagrams.

Built and Backed by Compoden

Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
