Heart Rate (Pulse) Sensor point void loop() {Heart rate data can be really useful whether you're designing an exercise routine, studying your activity or anxiety levels or just want your shirt to blink with your heart beat. The problem is that heart rate can be difficult to measure. Luckily, the Pulse Sensor Amped can solve that problem! The Pulse Sensor Amped is a plug and play heart rate sensor for Arduino. It can be used by students, artists, athletes, makers, and game & mobile developers who
