Alarm Buzzer

The Alarm Buzzer is a compact, high-impact audible module that delivers a loud beep or alarm tone from a small footprint — ideal for your TechBox kits when you want feedback, alerts, or sound effects. It arrives ready to plug into your breadboard with pre-soldered male jumper wires (Red & Black), making prototyping and classroom use fast and easy. What’s Included: Piezoelectric Alarm Buzzer Module – Self-contained sounder module optimized for alert tones. Pre-soldered Male Breadboard Wires – One red wire (Input) and one black wire (GND) already attached, ready for breadboard or jumper-wire connection. Module Features: Wide Operating Voltage – Works with a range of voltages suitable for breadboard microcontroller projects (e.g., 3 V to 24 V typical for piezo types). Minimal Wiring – Simple two-wire connection (input and ground); no complex wiring required thanks to pre-wired leads. Plug-and-Play Prototype Ready – Pre-soldered breadboard leads let students or hobbyis
