Programmable Pet Feeder - Arduino Uno + DS3231 RTC with Servo Dispenser

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

Leave for a weekend trip or a long office day without worrying about your pet's next meal. This kit lets you build a clock-driven feeding station that automatically dispenses a set portion of dry food at the times you program. The Arduino Uno reads the DS3231 real-time clock, compares it against your schedule, and triggers an SG90 servo to tip a hopper flap - exactly when your furry friend expects it.

What You'll Build

You will assemble and code a complete automatic pet feeder prototype. The system waits until a pre-set hour, then actuates the servo for a calibrated duration, releasing one portion of food. A 16�2 LCD connected via I2C shows the next scheduled feed time and the total portions dispensed so far. Three tactile buttons let you set the time, adjust feeding windows, or trigger a manual feed. Once finished, you'll have a working model ready to mount above a bowl, with all the logic you can later expand to IoT or a mobile app.

What You'll Learn

• Interface the DS3231 RTC with Arduino and configure multiple alarm-triggered events
• Control an SG90 servo with millisecond precision to dispense a consistent food portion
• Drive a 16�2 character LCD over I2C to display live schedule and portion status
• Integrate hardware debouncing for push-button user menus and manual override routines

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Ideal for CBSE Class 11-12 students building a home automation project, first- or second-year B.Tech (ECE/EEE) mini-project takers, and ATL Tinkering Lab participants. It also suits Smart India Hackathon teams prototyping a pet care solution and hobbyists from IIT/NIT/VIT/BITS who want a ready-to-test scheduling module before scaling to a PCB enclosure. Prior basic Arduino experience is helpful but not mandatory - the guided flow fills the gaps.

Built and Backed by Compoden
