When DC voltage is applied to the VCC and GND pins, the internal oscillator drives the piezo element at a fixed frequency (typically ~2.5 kHz), producing a continuous audible tone. The onboard signal pin connects through a transistor switching circuit, allowing a microcontroller GPIO pin to turn the buzzer on and off digitally. Because the oscillation is generated internally, you only need to send a simple HIGH or LOW signal - no need to write tone-generation code or use PWM timers. This makes the active buzzer module significantly easier to use than passive buzzers for basic alert and notification applications.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Choose This?\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e100% authentic module sourced from trusted, authorized suppliers\u003c\/li\u003e\n\u003cli\u003e1-5 day shipping, 7-8 day delivery across India from our Bengaluru warehouse\u003c\/li\u003e\n\u003cli\u003eSame-day delivery available within Bengaluru\u003c\/li\u003e\n\u003cli\u003eExpert technical support included - get help with wiring, code, and integration\u003c\/li\u003e\n\u003cli\u003eBeginner-friendly with extensive online resources and community support\u003c\/li\u003e\n\u003cli\u003eReliable performance backed by 7-day warranty on manufacturing defects\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003ePin Configuration\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePin\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eLabel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eDescription\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003ctd\u003eVCC\u003c\/td\u003e\n\u003ctd\u003ePower supply input (3.3V - 5V DC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003ctd\u003eGND\u003c\/td\u003e\n\u003ctd\u003eGround connection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e3\u003c\/td\u003e\n\u003ctd\u003eI\/O (Signal)\u003c\/td\u003e\n\u003ctd\u003eDigital input - HIGH to activate buzzer, LOW to deactivate (check module variant)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eWiring Guide - Arduino UNO\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBuzzer Module Pin\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eArduino UNO Pin\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVCC\u003c\/td\u003e\n\u003ctd\u003e5V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGND\u003c\/td\u003e\n\u003ctd\u003eGND\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eI\/O (Signal)\u003c\/td\u003e\n\u003ctd\u003eDigital\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhen will I receive my order?\u003c\/summary\u003e\n\u003cp\u003eProducts ship within 1-5 days from our Bengaluru warehouse.
