Heart Beat Demostration
BME 214L Learning Assistance
Overview
Objective
Create a device that utilizes a heartbeat sensor for a fun demonstration on Arduinos and sensors for freshman students
Process
Utilized a heart rate sensor and Arduino to measure heartbeat
Digitally filtered the signal by using a moving average algorithm and a high pass threshold
Created a CAD model in Fusion 360 for a gear and pinion so a heart can move linearly with a servo motor
Manufactured the device by 3D printing the CAD models
Result
The device was able to measure heart rate ranging from 80 bpm to 100 bpm
A heart icon was successful at “bouncing” to the heart rate
Students were very impressed and lots of smiles were shown during the demostration
