Put your finger on the heart rate sensor in the base, and an Arduino Nano actuates a single servo to your own personal beat. We’d love to see it work overtime while someone gets worked up.

Pulse oximetry is a non-invasive means for measuring blood oxygen saturation and pulse rate, with typical sensors based on rigid electronics. Here, the authors develop a pulse oximeter based ...

It works with all of the Teensy 3.x boards, and is able to handle accelerated synchronous and independent moves of multiple motors at the high pulse rates required for micro-stepping drivers.

Learn how to create a simple heart rate monitor using an Arduino Pro Mini, PulseSensor, and OLED display. This beginner-friendly project is perfect for learning basic electronics, sensors, and ...
