Multi-Zone Relay Scene Switcher Kit with Arduino Uno + Relay
Master Smart Home Automation: Build the Arduino Multi-Zone Relay Scene Switcher Kit
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 room and with a single button press, switching the lighting from energetic morning brightness to cosy evening warmth. This kit lets you build a four-zone relay controller that automates appliances based on time of day or manual tactile inputs, turning any space into a smart scene environment. Perfect for students prototyping real-world home automation or hobbyists wanting a reliable timer-driven relay system.
What You'll Build
A functional multi-zone relay unit with an LCD display showing the current active scene. Four relays can independently control lights, fans, or any low-power AC/DC device, switched by four tactile buttons or automatically scheduled via a DS3231 real-time clock. The system cycles through morning, afternoon, evening, and night scenes, each with its own set of relay states.
What You'll Learn
- How to interface a DS3231 RTC and schedule relay actions at precise times
- Relay switching with flyback diode protection and noise suppression
- Button debouncing and event-driven input handling for instant scene changes
- 16x2 LCD integration with I2C for real-time feedback and status display

Who This Kit Is For
Ideal for CBSE Class 11-12 students working on home automation projects, B.Tech ECE/EEE undergraduates for Smart India Hackathon prototypes, and ATL Tinkering Lab mentors seeking a ready-made relay control kit. Also perfect for hobbyists and IoT enthusiasts building time-based appliance controllers.
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 to access your AI build companion trained for this exact kit. It provides real-time wiring, code debugging, and video walkthroughs. You can also reach us via WhatsApp for human support.
What appliances can I control with the relays?
Each relay handles up to 10A at 250V AC, so you can safely control lamps, ceiling fans, tabletop appliances, or even a small water pump. The four zones can manage different parts of your room or separate devices for distinct morning, afternoon, evening, and night scenes.
Can I change the default morning/afternoon scene times?
Yes, the Arduino sketch is fully customisable. The AI companion shows you exactly which line to modify for each time trigger, so you can set scenes to match your daily routine.
Is this kit suitable for CBSE or engineering project submissions?
This kit aligns with CBSE Class 12 computer science practicals and B.Tech ECE/EEE mini projects. It demonstrates real-time clock interfacing, relay driver circuits, and input handling — key topics in smart home automation courses.
Four relay zones as morning afternoon evening and night scenes. Button or RTC time triggers each scene.
