A real-time heart rate monitor that simulates PPG (photoplethysmogram) signals, detects individual heartbeats, and calculates BPM using peak detection algorithms similar to clinical pulse oximeters.

1. Generates realistic PPG waveform - Simulates blood volume changes each heartbeat
2. Detects peaks - Identifies individual heartbeats using threshold and timing
3. Calculates BPM
4. Displays live graph - bar graph of
