5V Active Buzzer Module for Arduino (Alarm/Beep) | KY-012
The loudest and easiest way to add sound to your project. This Active Buzzer module creates a loud beep as soon as you give it power. Unlike "Passive" buzzers that need complex code to make sound, this one is simple: High = Beep, Low = Silent.
-
Type: Active (Internal Oscillator).
-
Voltage: 3.3V - 5V DC.
-
Sound: Loud continuous tone (approx 2.5kHz).
-
Best For: Alarms, Timers, and Button Feedback.
LM358 Dual Op-Amp IC | Low Power Operational Amplifier (DIP-8)
The industry-standard chip for audio and signals. The LM358 contains two independent, high-gain operational amplifiers in a single 8-pin package. Unlike the older 741 Op-Amp, the LM358 is designed to work perfectly with a single power supply (like a battery).
-
Package: DIP-8 (Breadboard Friendly)
-
Supply Voltage: 3V to 32V
-
Best For: Pre-amplifiers, Active Filters, and Line Following Robots (Comparator).
Sound Sensor Module (Microphone) | Clap Switch & Alarm Detector
Turn on lights with a clap! This microphone module detects sound waves and converts them into a digital signal for your Arduino. It is the core component for "Clap Switch" projects and noise-activated alarms.
-
Sensitivity: Adjustable via Blue Potentiometer.
-
Outputs: Digital (Gate) and Analog (Waveform).
-
Microphone: High-Sensitivity Condenser Mic.
-
Best For: Clap Switches, Baby Monitors, and Noise Alarms.
