From f3710c58ff19c11c6acd444f3aae78f1587cb31d Mon Sep 17 00:00:00 2001 From: Akfreak Date: Thu, 4 Dec 2014 02:00:23 -0800 Subject: [PATCH] Update Buzzer.md I added information to help anyone who runs into the same problem I did, the buzzer not functioning after trying multiple devices. I researched and saw you need to have 5v power to the board. The ESC connection is a simple place to power the board when working on the flight controller on a bench. This allows you to use the buzzer for conformations. Please see added text and link to a Radio Shack (local US electronics retailer) buzzer. --- docs/Buzzer.md | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/docs/Buzzer.md b/docs/Buzzer.md index a0ab3d4a47..642ec566ca 100644 --- a/docs/Buzzer.md +++ b/docs/Buzzer.md @@ -20,13 +20,14 @@ Examples of a known-working buzzers. * [Hcm1205x Miniature Buzzer 5v](http://www.rapidonline.com/Audio-Visual/Hcm1205x-Miniature-Buzzer-5v-35-0055) * [5V Electromagnetic Active Buzzer Continuous Beep](http://www.banggood.com/10Pcs-5V-Electromagnetic-Active-Buzzer-Continuous-Beep-Continuously-p-943524.html) - + * [Radio Shack Model: 273-074 PC-BOARD 12VDC (3-16v) 70DB PIEZO BUZZER](http://www.radioshack.com/pc-board-12vdc-70db-piezo-buzzer/2730074.html#.VIAtpzHF_Si) ## Connections ### Naze32 -Connect a supported buzzer directly to the BUZZ pins. Observe polarity. +Connect a supported buzzer directly to the BUZZ pins. Observe polarity. Also if you are working with flight controller outside of a craft, on a bench for example, you need to supply 5 volts and ground to one of the ESC connections or the buzzer will not function. + ### CC3D
