Buy Audio Boards Online in India

Devices that enhance the listening experience are known as audio components. Audio components consist of a wide range of amplifiers, receivers, and adapters that improve the quality of sound from various source components. Various types of audio amplifiers are available with different power ratings, channel and connection types, control setups, and built-in effects. It is recommended to select amplifiers that deliver at least twice the program power rating of your speakers to achieve efficient and consistent amplification results. Buy Audio Boards and other electronic modules online in India.

Arduino Audio Amplifier – Wiring & Code Example

Basic Wiring (e.g., PAM8403 / LM386 module)

Connections:

Amplifier VCC → Arduino 5V

Amplifier GND → Arduino GND

Amplifier IN+ → Arduino D9 (audio/tone output pin)

Amplifier IN- → GND

Speaker + → Amplifier OUT+

Speaker - → Amplifier OUT-

Note: Use an 8Ω speaker (or as specified on the module). Keep wires short for best audio quality.

Simple Tone Test Code (Arduino)

const int audioPin = 9; void setup() { pinMode(audioPin, OUTPUT); } void loop() { tone(audioPin, 1000); // 1 kHz tone delay(500); noTone(audioPin); delay(500); }

Amplifier Module Power & Output Comparison

Module Type	Typical Power Output	Channels	Speaker Impedance	Ideal Use Case
Small LM386 Module	~0.5–1 W	Mono	8Ω	Simple buzzers, small speakers
PAM8403 Amplifier	~2×3 W (stereo)	Stereo	4–8Ω	Mini stereo speakers, DIY Bluetooth box
TDA7297 / 15–20 W	2×10–15 W	Stereo	4–8Ω	Larger speakers, desktop amps
Class D 30 W+ Boards	30 W and above	Mono / Stereo	4–8Ω	High-volume projects, outdoor use

DIY Sound Projects for STEM Education

Sound-Effect Box – push buttons trigger different tones or recorded sounds through a small speaker.

Morse Code Trainer – use a buzzer/speaker and LEDs to teach Morse code and timing.

Simple Intercom – two Arduino nodes with mic + amp + speaker to talk over a wired connection.

Noise Level Indicator – microphone module + LEDs to show loud/quiet environments.

Talking Thermometer – temperature sensor + audio prompts (“Hot”, “Cold”) via sound module.

Alarm Project – combine PIR sensor + audio module + amplifier for motion-triggered alarm.

Passive Buzzer Module 3.3V-5V DC
