Buzzer
OrniFlight supports active buzzers for audible status indication and lost-model location.
Functions
- Arm/Disarm — distinct tones
- Low Battery — repeating warning beeps
- Failsafe — SOS pattern
- Lost Model — continuous beeping via switch
- GPS Fix — confirmation tone on satellite lock
- Calibration — beep patterns during gyro/accel calibration
- RX Signal Lost — warning when receiver connection drops
Hardware
- Connect a 5V active buzzer (NOT a passive piezo) to the BUZZ- and BUZZ+ pads

Ornithopter Safety
The beeper is especially useful for large ornithopters that may land in tall grass or foliage. Configure the BEEPER mode on a momentary switch for quick activation when needed.
