Ever had your heart rate measured with one of those sensors in the doctor?s office? In this mission, you?ll build your own, using a pulse sensor and laser cut wood to construct your own personal wearable device! Plus as you help Pip and Dr. Lizard power Piperbot up in our narrative based on planet Trezed, you?ll learn how your heart pumps blood throughout your body, a foundational biomedical concept. This kit includes the Heart Rate Sensor lesson free and accessible on make.playpiper.com. The Heart Rate Sensor is an add-on and REQUIRES a Piper Make Starter Kit with the Raspberry Pi Pico to get started (sold separately).
