Motorised Pet Door Kit with Arduino Uno + Servo
Motorised Pet Door Kit: Arduino Servo Force-Sensing Control
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Create a safe, motorised pet door that automatically stops closing when it senses an object—preventing crushed treats or hurt paws. This kit teaches force feedback loops using a servo, FSR pressure sensor, and Arduino, all while building a functional prototype for pet safety. Ideal for CBSE Class 12 projects, ATL tinkering, or B.Tech ECE assignments, it turns theory into a tangible, force-sensing gripper.
What You'll Build
You’ll assemble a motorised pet door with a gripper jaw driven by an SG90 servo. A Force-Sensitive Resistor (FSR) mounted on the jaw tip measures pressure continuously; the Arduino reads the analogue force and stops the servo motor exactly when the pre-set threshold is reached. A 0.96-inch OLED screen displays real-time force values (in grams) and door status. The result is a door that gently closes on a dog biscuit, a fragile egg, or a child’s toy without crushing it—all governed by your own force calibration.
What You'll Learn
- Interface a Force-Sensitive Resistor (FSR) and read analogue pressure values with Arduino
- Map sensor readings to servo angle and implement closed-loop position control
- Program a force feedback loop that stalls the servo at a target grip force
- Calibrate force thresholds using code-based tuning or an onboard potentiometer
- Display real-time sensor data and door status on an I2C OLED screen

Who This Kit Is For
This intermediate-level kit is designed for students aged 15–18 tackling CBSE Class 12 projects, ATL Tinkering Lab innovators, and first-year B.Tech ECE/EEE enthusiasts. It is equally suited for Smart India Hackathon teams needing a force-actuated mechanism or makers prototyping assistive pet feeders. If you’ve already built a basic LED-blinking circuit and want to conquer sensor feedback and servo control, this is your next 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?
Simply scan the QR code on the box to launch your AI companion, which provides step-by-step assistance specific to this kit. You can also send a message on WhatsApp for direct help from our engineering team.
Can I adjust the force sensitivity for different objects?
Yes, the Arduino sketch includes a variable threshold you can modify. The OLED screen shows real-time force, so you can fine-tune the value for a biscuit, an egg, or anything in between.
Does this kit require soldering?
No, all connections are made on the included 400‑point breadboard using jumper wires. The OLED and servo connect via pin headers, so no soldering iron is needed.
Is this kit suitable for a CBSE project or science exhibition?
Absolutely. It covers sensor integration, motor control, and data display—core concepts in CBSE Class 12 Physics and Computer Science. The working prototype demonstrates force feedback and closed‑loop control, which often scores high marks in evaluation rubrics.
Pet Smart Door — FSR sensor on gripper jaw closes servo until target force reached. Prevents crushing fragile objects.
