Automatic Pet Feeder Plus Kit with Arduino Uno + Servo
Automatic Pet Feeder Plus Kit: Arduino-Driven Servo Finger with Camera Positioning
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Missing your pet while away? This kit lets you build a camera-equipped automatic feeder that uses three servos and fishing line tendons to flex a silicone finger through 3D space — precisely delivering food on schedule. The OV2640 camera estimates the finger’s position, ensuring reliable, controlled feeding every time without guesswork.
What You'll Build
A fully functional pet feeder with a tendon-driven silicone finger that moves in three dimensions. The Arduino Uno coordinates three SG90 servos via a PCA9685 driver, while the camera feeds position data to keep the finger’s motion accurate. Once assembled, you can program timed feedings, monitor the finger’s reach, and adjust the movement path — perfect for pets left at home during work hours or overnight.
What You'll Learn
- Designing tendon-driven robotic actuators with fishing line and multiple servos
- Multiservo coordination using a PCA9685 driver and Arduino Uno for synchronized motion
- Integrating camera feedback (OV2640) for real-time position estimation in a robotic end-effector
- Prototyping and soldering a permanent electronics board for a reliable, long-term pet care device

Who This Kit Is For
This advanced kit is built for engineering students in B.Tech ECE/EEE programs at institutions like IITs, NITs, VIT, and BITS who want hands-on experience with motion control and robotic actuation. It’s also perfect for Smart India Hackathon participants working on pet care or automation projects, or for CBSE Class 12 students with a serious robotics hobby looking to tackle a real-world challenge.
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?
Our AI companion walks you through troubleshooting step by step, and our team is on WhatsApp for quick personalized help.
Can I use the silicone mould to create a custom feeder shape?
Yes, the silicone kit lets you cast a fingertip. You can design your own mould shape for different food types or pet sizes.
Is programming knowledge required?
Basic Arduino programming is needed; our AI companion includes sample code for camera-servo coordination to get you started quickly.
Does the kit work with other microcontrollers like ESP32?
The included driver and camera are compatible, but you'll need to adapt the code and wiring; we recommend sticking with Arduino Uno for this project.
