LM386 Audio Amplifier Module

The LM386 Audio Amplifier Module is a compact and low-power audio amplifier designed to amplify audio signals in various electronic projects. It is ideal for use in small audio applications such as radios, musical projects, and sound systems. The module is easy to integrate and provides high-quality audio amplification with minimal power consumption.

Applications:

• Portable audio systems and speakers
• DIY radios and musical projects
• Low-power sound systems
• Audio amplification in microcontroller-based projects

Key Features:

• Low-power consumption (operates with a supply voltage as low as 5V)
• Compact size ideal for portable and space-constrained projects
• Amplifies audio signals with minimal distortion
• Compatible with various audio sources (e.g., microphones, audio output from microcontrollers)
• Built-in gain adjustment for volume control

Pinout Description:

• VCC (Pin 6): Connect to a power supply (5V to 12V).
• GND (Pin 4): Ground connection.
• Input (Pin 3): Audio signal input.
• Output (Pin 5): Audio output signal to speaker.
• Gain (Pin 1): Adjustable gain to control volume.

Whether you're building a portable speaker or incorporating audio functionality into a larger project, the LM386 Audio Amplifier Module is a reliable and efficient solution for clear sound amplification.

Sample Code for Arduino:

// LM386 Audio Amplifier Example

void setup() {
    pinMode(9, OUTPUT); // Set audio output pin
}

void loop() {
    // Generate a tone on pin 9 to test the audio amplifier
    tone(9, 1000, 500); // 1000 Hz for 500ms
    delay(1000);
}
