IR Controlled Home Theatre Switcher Kit with Arduino Uno + Relay
Arduino IR Home Theatre Switcher Kit: Control Your AV Setup with Any Remote
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 walking into your home theatre and switching between your set-top box, gaming console, and streaming stick with a single universal remote. That’s exactly the kind of seamless control this Arduino Uno-powered kit lets you design. You’ll build a dedicated 4-channel IR switcher that reads codes from any IR remote, toggles relay outputs, and displays the active device on a bright 16x2 LCD screen. It’s a practical embedded systems project that teaches real-world hardware-software integration, not just blinking LEDs.
What You'll Build
You’ll assemble a compact control hub that sits between your AV sources and display. Point any IR remote at the TSOP1738 receiver, and the Arduino decodes the signal, processes the mapped action, and triggers the corresponding relay channel. The LCD updates instantly to show which device is live—handy when you can’t see the source equipment. The circuit is built on a breadboard for easy reworks, and the included 12V adapter powers the whole setup reliably.
What You'll Learn
- Decode IR protocols using the TSOP1738 sensor and map hex codes to specific actions
- Interface a 4-channel relay module with inductive load protection via 1N4007 diodes
- Drive a 16x2 LCD over I2C for clutter-free wiring and real-time status display
- Structure Arduino code for state-based control logic used in home automation

Who This Kit Is For
This intermediate kit is tailored for Indian students and makers ready to move beyond basic Arduino tutorials. CBSE Class 11–12 learners and B.Tech ECE/EEE students will find it ideal for embedded systems coursework and mini-projects. It’s also a strong fit for Smart India Hackathon teams tackling home automation themes, ATL Tinkering Lab educators demonstrating IR protocols, and hobbyists from IIT, NIT, VIT, or BITS Pilani looking for a weekend challenge with a tangible outcome.
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?
The AI companion offers real-time debugging tips, and you can reach our team via WhatsApp for hands-on support. We’ll help you diagnose wiring, code, or component issues.
Can I use any IR remote with this kit?
Yes, the Arduino sketch includes a code-mapping routine that learns button presses from any standard IR remote—TV, AC, or the included generic remote—so you can repurpose your existing one.
Will this safely control high-voltage AV devices?
The 4-channel relay module provides galvanic isolation between the low-voltage control circuit and the appliance side. The included 1N4007 diodes protect against voltage spikes, but always follow the relay’s rated current and voltage limits for your AV gear.
Can I expand beyond four devices later?
The relay board handles four independent channels, but you can stack additional modules using the Arduino’s spare digital pins and extend the code logic. The core IR decoding and LCD feedback structure remains the same.
IR remote controls 4-channel relay board to switch AV devices. LCD shows active device name. Teaches IR code mapping.
