The haptic module controls a high current driver to power a motor or buzzer (or similar devices).

In the MMR+ model, the coin vibration motor provides haptic feedback by vibrating using the haptic module.

Functions are defined in the haptic.h header filer. Circuit diagrams for the driver pin are in section 8 of the product specification.

# Run buzzer for 7500ms
libmetawear.mbl_mw_haptic_start_buzzer(board, 7500)

# Run motor at 100% strength for 5000ms
libmetawear.mbl_mw_haptic_start_motor(board, 100.0, 5000)

The haptic module does not provide PWM (pulse-width modulation) capability.
