IR Remote Code Decoder Kit with Arduino Uno
IR Remote Code Decoder Kit — Decode Any Infrared Remote and Display Its Secret Codes
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine pointing any TV, AC, or set-top box remote at a small receiver and instantly seeing the exact infrared code that each button sends — the protocol name, device address, and command value — displayed clearly on a 16x2 LCD screen. This kit lets you uncover the hidden language of remote controls and understand how they communicate with appliances. Whether you're curious about reverse-engineering your AC remote or want a foundation for custom home automation projects, this project transforms the invisible IR signals into readable data.
What You'll Build
You'll assemble a standalone IR decoder that captures infrared signals from any remote control, decodes the raw timing into standard protocols like NEC, Sony, and RC5, and prints the protocol type, address, and command on a backlit LCD. The final unit runs on a 9V battery, so you can carry it around the house and test every remote you own.
What You'll Learn
- How infrared remotes encode button presses as pulses of light
- How to capture and decode IR signals using the TSOP1738 receiver
- Displaying real-time data on a 16x2 LCD via I2C backpack
- Interpreting common IR protocols like NEC, Sony, and RC5

Who This Kit Is For
This kit is designed for young makers aged 10 and above — ideal for CBSE Class 11-12 students exploring electronics, B.Tech ECE/EEE mini projects, and participants in Smart India Hackathon or ATL Tinkering Lab challenges. It requires no prior soldering or coding experience, making it a perfect weekend activity for curious kids and parents.
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.
What if I get stuck during the build?
Scan the QR code on the box to access the AI companion that knows every detail of this kit. You can also send a WhatsApp message with a photo of your circuit, and our engineers will guide you to the next step within hours.
Can I decode any brand's remote with this kit?
Yes, the TSOP1738 receiver works with most consumer infrared remotes, including TV, AC, set-top box, and projector brands. The code displays protocol, address, and command, making it truly universal.
Is this kit suitable for a complete beginner?
Absolutely. The project uses an Arduino Uno with pre-tested components, and the AI companion guides you through wiring and code step by step. No prior soldering or coding experience is required.
How can I use the decoded codes later?
Once you know the codes, you can build your own custom IR controller, clone a remote, or integrate it into home automation projects. The AI companion can suggest next steps based on your goals.
TSOP1738 decodes any IR remote and shows protocol, address and command on LCD. Universal decoder.
