ESP8266_KY-012_Active_buzzer_module

The active buzzer ( KY-012 ) continuously makes sound and only needs power to function.
I already had tested this buzzer module with my Arduino.

Testing buzzer direct connecting to power  ( 3.3 V )
  • module Pin  -    VCC
  • Pin (middel) not connected
  • module Pin S     GND
Module gives sound, volume low !!


With ESP8266Basic program :
  • Pin - ESP output pin
  • Pin (middel) not connected
  • Pin S ESP8266 Ground 
Using the ESP8266Basic program below
 [Pin Buzzer High] button switches my buzzer on.
 [Pin Buzzer Low] button switches my buzzer off.

end


Alternatively you can connect
  • Pin - ESP VCC ( 3V3 )
  • Pin (middel) not connected
  • Pin S ESP8266 output pin 5 
Using the same ESP8266Basic program
 [Pin Buzzer High] button switches buzzer off.
 [Pin Buzzer Low] button switches buzzer on.
