Signal Coach

Connect Arduino, ESP32, or any supported pulse-wave serial stream. Chrome finds the beats, coaches the signal, and shows BPM only after it settles.

Supported pulse streams

Signal Coach needs a numeric pulse-wave sample. It accepts one number per line, S512, Signal 512, signal=512, timestamp,signal, JSON samples, Arduino signal,bpm,ibi,beat, and PulseLink PSWS. Sender BPM and IBI never control the coach.

Choose the rate your sketch prints. The default tutorial sends 50 samples each second.
