Open Insulin Pump Controller Kit with Arduino Nano + Stepper Motor
Advanced Closed-Loop Insulin Pump Controller Kit: Arduino Nano, Stepper Syringe, BLE CGM Interface
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
You'll assemble a functional research prototype of an open-source insulin pump controller. The system reads glucose levels wirelessly from a continuous glucose monitor (CGM) over Bluetooth Low Energy, then precisely drives a syringe pump using a PID algorithm to simulate insulin delivery. This kit is built for serious biomedical experimentation, giving you a hands-on understanding of automated hormone dosing, sensor fusion, and safety-critical embedded design.
What You'll Build
A bench-top closed-loop insulin delivery research platform. You'll 3D-assemble a syringe mount, wire the Nano, stepper driver, OLED, RTC, and SD logger, then pair it with a BLE glucose source. The result is a system that calculates insulin doses in real time, drives a NEMA 17 stepper to dispense minute volumes, and logs every decision to microSD — a complete model for diabetes technology prototyping.
What You'll Learn
- Implement a PID control loop to convert glucose readings into stepper motor steps
- Interface a CGM over BLE using the HC-05 and parse real-time glucose values
- Calibrate a syringe pump for microliter dosing with NEMA 17, A4988 microstepping, and INA219 current monitoring
- Log treatment data with DS3231 RTC timestamps on microSD for analysis and audit trails

Who This Kit Is For
Biomedical engineering students and research scholars at Indian universities building diabetes management or drug delivery prototypes. Engineers in medical device startups testing closed-loop algorithms. Smart India Hackathon teams tackling healthcare automation. Anyone with embedded C skills who wants to move from theory to a working insulin dosing model — not a toy, but a serious research instrument.
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 inside the box to launch the AI build companion, which walks you through each wiring and calibration step. You can also send photos via WhatsApp for quick human assistance.
Is this a certified medical device?
No. The kit is for research, education, and prototyping only. It is not intended for human use or clinical therapy.
What CGM can I use with this kit?
Most Bluetooth-enabled CGMs that expose glucose data via standard BLE characteristics. The companion software includes a sample parser and calibration routine; you can adapt the code for your specific sensor.
How accurate is the syringe dosing?
With A4988 microstepping and the 3D-printed mount, you can achieve repeatable dose increments of approximately 0.01 mL. Fine-tuning depends on your syringe choice and mechanical alignment, which the AI guide helps you calibrate using the INA219 current readings.
Nano controls stepper-driven syringe. CGM glucose input over BLE. Closed-loop PID insulin dosing model.
