« on: February 18, 2018, 03:34:43 pm »
I' m tryng to configure buzzer working with revo board...but when i connect the battery he activated and won't stop buzzing!!
Ok more details:
The board is Revo, the buzzer is the hobbyking 3 wire(as suggested)
The buzzer is connected to flight controller n*5 pwm output.
The receiver is an SBus frsky
The FC is alimentated from a matek PDB with 5v through pwm output n*6
I've read all about how configure it on librepilot documents....and did it.

I've already connected these buzzer on a cc3d and works great....but now i can't replicate on revo....

Sorry for my english

Strange... your config looks fine.
Be sure the Accessory1/ch7 move in Input tab according to the switch you want to use for buzzer.
Connect a servo to the Output5 and see what happens.

I tried with a servo and works perfectly. So the FC, the radio settings and the pwm/output settings are fine.
I decide to take a buzzer from another drone and.... it WORKS !!

The strange things is,  the buzzer that is working,  is identical to the 3 buzzers that won't...all 4 bought from HK in two different times.

What's wrong ? different buzzer settings? or simply broken!!

How you can spend time with just a toy :)

Just for test you can increase the range for output5 and see if stops at some point.
900-2100, 800-2200...
Another option for testing over all the range, go to the output tab, start a "Test Outputs" and manually change the output5 using the slider.
Be sure you do not move a slider's motor while propellers are mounted!

I recall some of them stop working if voltage is just above +5V but this one always works, maybe something broken inside.

Done...i've expanded the pwm range at is maximum range.
LibrePilot  give a range from 500 to 2500 and with live test output enabled i tried....result?
No way to stop buzzing!!

I'll buy a new one, but different, was thinking a matek buzzer

Really thanks for your advice😄
