Automated Night Mode Kit for Bedroom – Arduino Uno, LDR, RTC, and PIR in One Pre-tested Project

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

Turn your bedroom into a hands-free sleep sanctuary. This kit guides you through building a bedside control unit that reads the room’s light level, the time of day, and your presence, then takes action: it dims your bedside lamps and switches on a heating or cooling relay exactly when you want to drift off. No separate modules to hunt for – everything from the Arduino Uno to the OLED display arrives in one box, pre-verified to work together.

What You'll Build

You’ll assemble and program a module that sits next to your bed. When the clock reaches your preset bedtime, the system checks whether the room is already dark using the LDRs and whether you’re in the room via the PIR. If it’s late and you’re still there, it gently dims the connected lights via relay and switches a second relay that can control a thermostat, heater, or fan – creating the ideal sleep environment without lifting a finger. The OLED screen shows the current time, ambient light percentage, and system status in real-time.

What You'll Learn

• Reading analog light levels with two LDRs and setting action thresholds in code
• Interfacing the DS3231 real-time clock and scheduling tasks at exact times of day
• Detecting motion using the HC-SR501 PIR sensor to trigger logic only when the room is occupied
• Controlling a 4-channel relay module with Arduino digital outputs to switch real appliances safely

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Ideal for CBSE Class 11-12 students looking for a working physics or computer science project, first-year B.Tech ECE/EEE students exploring embedded systems, ATL tinkering lab participants, and hobbyists building real home automation. The intermediate code and wiring makes it a strong submission for Smart India Hackathon prototype rounds or a hands-on showcase in NIT/IIT/VIT labs.

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.
