Build a 4-Channel Programmable Power Strip with Arduino Uno and Real-Time Clock Schedules

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 a standard electrical strip into a smart power hub where each socket follows its own timetable. This kit combines an Arduino Uno, a precision DS3231 RTC, and a 4-channel relay module to give you independent scheduling for up to four appliances. A 16x2 LCD shows custom channel names and active on/off times, navigated with tactile buttons—no smartphone or cloud dependency required.

What You'll Build

You’ll wire and code a standalone programmable power strip. Each relay channel can have multiple daily on/off periods stored in non-volatile memory, making it perfect for automating fish tank lights, periodic router reboots, or shutting off computer monitors after study hours. The LCD interface lets you scroll through channels, edit schedules, and override relays manually with instant feedback.

What You'll Learn

• Programming a DS3231 real-time clock module to trigger precise events
• Driving a 4-channel relay module safely with Arduino digital pins
• Building a multi-level menu system on a 16x2 LCD with I2C backpack
• Debouncing tactile switch inputs and using EEPROM to store schedules
