Description
The 5V Buzzer is a compact, low-power sound-emitting device designed for use with microcontrollers, Arduino, ESP32, Raspberry Pi, and other circuits. It can operate on a 5V DC supply and generates a clear, audible beep when voltage is applied. It is ideal for alarms, timers, indicators, and DIY electronics projects requiring audio feedback.
