Hello,
I don’t thought many when I saw BZ110DB_WS2812 5V 110DB Super Loud Active Buzzer with WS2812 LED Light for RC Drone , just added to the cart and bought. After months spent on shipping pkg has arrived, but I don’t know how to use it.
When I have ordered it I don’t think that there is something special, I thought that I can put it into any GPIO output of ESP32/8266 but… I don’t know how to connect it.
So, the 5v IN voltage is clear for me, but there are 2 additional pads, and another one on edge named “OUT”.
Do anyone could help me investigate how to cnnect it ?
Of course I don’t want to use it as drone signal, I wan’t to integrate it as a some kind of loud alarm/siren.
ANy help would be more than helpfull
regards
