Medispenser
Embedded Hardware
An automated pill dispenser designed for use in clinical and assisted care environments. An RFID reader looks up the patient's prescription, and three slotted-disk hoppers driven by steppers dispense the correct combination and dosage, with an Arduino-controlled LCD guiding the nurse or caregiver through the workflow.
Built with a team of four for Cornerstone 2. The final prototype achieved 100% dispensing accuracy across 100 trials of three patient prescriptions, exceeding the 95% initial target. Total build cost: ~$70 — far below the cost of commercially available solutions.
For this project I worked on CAD design, 3D printing, and laser cutting. I assembled the Arduino components of the system and programmed the controller using Arduino C++.
