Active Buzzer Alarm Module Sensor Beep Smart Car DIY for Arduino DC3.3-5V

Bmonster Laboratory here today we're  going to create a sound sensor activated   active buzzer alarm using our Elegoo mega 2560  microcontroller let's get started now there   definitely are other components you can add in  place of or in addition to an active buzzer in   a project like this so we'll definitely be  revisiting something like this in the future   using a sound sensor module but for now we're  going to create a sound activated buzzer alarm   we're going to take a look at the wiring the code  and see how it works if you saw last week's video   i did add a couple new components here the one  component i added is a an active buzzer and the   other component i added is a 220 ohm resistor  at the ground connection for my active buzzer   the active buzzer has oscillating circuits  and operates on a simple dc electric signal   whereas a passive buzzer operates on a square  wave fr
