Wearable Arduino Heart Rate Monitor

The video tutorial explains how to create an Arduino-based heart rate monitor using a pulse sensor and LEDs. The pulse sensor detects heartbeats by measuring reflected green light, which is processed by Arduino code to animate a heartbeat pattern with LEDs. The project uses a LilyPad Arduino, suitable for e-textiles, and is powered by a small lithium battery for portability. The device can be worn on a headband or attached to various body parts for monitoring.
