5V Active Buzzer Module – Loud & Reliable Sound

5V Active Buzzer Module for Arduino (Alarm/Beep) | KY-012

Original price was: ₵6.00.Current price is: ₵5.00.

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 Operational Amplifier

LM358 Dual Op-Amp IC | Low Power Operational Amplifier (DIP-8)

Original price was: ₵8.00.Current price is: ₵5.00.

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 3 pin Digital Output

Sound Sensor Module (Microphone) | Clap Switch & Alarm Detector

₵15.00

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.

Buy Audio Amplifiers, Op-Amps & Sound Modules in Ghana

Sound brings a project to life. Whether you are building a "Clap Switch," a pre-amplifier, or a portable speaker, you need the right components. At DIYGH, we stock both ready-to-use modules for beginners and discrete audio ICs for engineers designing custom circuits.

1. Audio ICs & Operational Amplifiers (Op-Amps)

  • LM358 (Dual Op-Amp): The versatile workhorse. Essential for building microphone pre-amplifiers, active filters, and signal conditioning circuits before the main amplifier.
  • LM386 (Audio Power Amp): The legendary 8-pin chip found in every beginner electronics textbook. Perfect for driving a small speaker from a battery.
  • TDA Series & NE555: We stock various audio-capable chips for tone generation and higher power amplification.

2. Amplifier Modules (Ready-to-Use)

  • PAM8403 (Class D): The #1 choice for portable speakers. This tiny board runs off 5V (USB) and is much more efficient than older analog amps.
  • DFPlayer Mini: A complete MP3 player in a small module. Load MP3 files on an SD card and trigger them with your Arduino.

3. Input & Output Devices

  • Mini Speakers (4Ω / 8Ω): Compact speakers that fit perfectly into 3D printed cases.
  • Electret Microphones: High-sensitivity mics. Pair these with an **LM358** to build your own sound sensor or voice recorder.

Why Buy Audio Parts from DIYGH?
Audio circuits are sensitive to noise. We stock authentic ICs and quality modules to ensure your sound is clear, minimizing the static and "hum" often found in cheap knock-off parts.
