loud 5v Buzzer alarm for drone. Perfect for Naze32, betaflight, cleanflight, Multiwii or Arduino

Description

Use this buzzer with the Naze32 to have it alert you to low voltage, act as a lost model alarm, indicate profiles & more.

Here is the latest buzzer code from Baseflight.  This code explains what the sounds mean. It may have been updated, so I encourage you to read your code to understand exactly what the buzzer is indicating.

* BUZZER_BAT_LOW – Warning beeps when battery is getting low (repeats)
* BUZZER_TX_LOST_ARMED – Beeps SOS when armed and TX is turned off or signal lost (autolanding/autodisarm)
* BUZZER_TX_LOST – Beeps when TX is turned off or signal lost (repeat until TX is okay)
* BUZZER_DISARMING – One beep when disarming the board
* BUZZER_ARMING – One beep when arming the board
* BUZZER_ARMING_GPS_FIX – Beep a tone when arming the board and GPS has fix
* BUZZER_TX_SET – Beeps when aux channel is set for beep or beep sequence how many satellites has found if GPS enabled.
* BUZZER_ARMED – Warning beeps when board is armed. (repeats until board is disarmed or throttle is increased)
* BUZZER_ACC_CALIBRATION – ACC inflight calibration completed confirmation
* BUZZER_ACC_CALIBRATION_FAIL – ACC inflight calibration failed
