Automatic Pet Feeder with Log: Build a Scheduled Arduino Pet Feeder with Data Logging

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 leaving your pet for a weekend and returning to a detailed log of every meal dispensed right on schedule. This kit walks you through building an automatic feeder that uses a DS3231 real-time clock to trigger an SG90 servo at three preset meal times, then stores each feed event with a timestamp in Arduino’s EEPROM. Designed for intermediate learners, it’s the perfect blend of practical automation and sensor-driven programming.

What You'll Build

You’ll assemble a fully functional pet feeder that serves dry food three times a day without manual intervention. The circuit reads the RTC to know the exact time, rotates the servo to open a dispenser or container lid, and immediately logs that event to the onboard memory. A 16x2 LCD shows the current time, the next meal, and the most recent feed log, giving you complete visibility.

What You'll Learn

• Interface the DS3231 RTC module to keep accurate time even during power loss
• Program an SG90 servo motor to precisely deliver a measured amount of food
• Log feed events to Arduino’s internal EEPROM with timestamps for later review
• Use tactile buttons and an I2C LCD to set meal times and navigate a simple menu
