Smart Pet Feed Dispenser Kit
Smart Pet Feed Dispenser Kit – Arduino‑Powered Soft Actuator with Force‑Pressure 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.
Create a pet feeder that thinks in terms of pressure and force, not just timers. This kit teaches you to inflate a silicone soft actuator using a peristaltic pump, measure the exact pressure with an MPX5010 sensor, and capture the force exerted via a load cell. The entire cycle—from pressure ramp to force reading—gets timestamped and written to a microSD card by an Arduino Uno, giving you a closed‑loop understanding of soft actuation for real‑world pet care.
What You'll Build
A fully functional dispenser where a soft, finger‑like actuator gently pushes food out of a hopper. You’ll program inflation cycles triggered by an RTC schedule, monitor pressure in real time on the OLED, and log force‑pressure curves to analyse how much food is dispensed per stroke. The result is a documented, repeatable soft‑robotic feeder that works without crushing kibble.
What You'll Learn
- Characterising a soft actuator: pressure vs. displacement and force relationships
- Interfacing the MPX5010 pressure sensor with Arduino for analogue‑to‑digital conversion and calibration
- Setting up a load cell with HX711 amplifier to measure gram‑level pushing force
- Scheduling autonomous actions with a DS3231 RTC and logging structured data to microSD for later analysis

Who This Kit Is For
Ideal for B.Tech ECE/EEE students prototyping soft robotic systems for projects or Smart India Hackathon, as well as IIT/NIT/BITS/VIT teams exploring compliant actuators. Makers in ATL Tinkering Labs and CBSE Class 11–12 science enthusiasts with soldering experience will also find this kit bridges the gap between textbook theory and a working pet‑care device while teaching data‑logging discipline.
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?
Scan the QR code to chat with the AI companion that knows every wire and calibration step, or message our support on WhatsApp for personalised guidance.
Do I need to buy a silicone soft actuator separately?
No. The kit includes a soft actuator designed to be inflated by the peristaltic pump. The build guide shows how to mount it and ensure an airtight seal.
Can I change the feeding schedule after programming?
Yes. The RTC schedule is controlled by the Arduino sketch. You can easily adjust times and portion sizes through the code, and the OLED displays the next‑feed countdown.
How is the force‑pressure data used for calibration?
You’ll record force readings at incrementing pressure setpoints. The data on the SD card lets you plot a calibration curve, so future builds can control food quantity by targeting a specific pressure level.
