DIY Speaker Amplifier Using LM386 | Electronics for Beginners | VinVout

@vinvout

🎶 Want to make your own mini speaker amplifier? In this video, we’ll build a simple yet powerful audio amplifier using the LM386 IC. Perfect for beginners, students, and hobbyists – this project shows how to boost audio from your phone or music player and drive a small speaker.

🔊 What you’ll learn in this video:

Understanding the LM386 audio amplifier IC

Why we use capacitors like 10µF, 100µF, and 1000µF

How to connect pins 2, 3, 5, 6, 7, 8 properly

Setting the gain of LM386 (using capacitor between pins 1 & 8)

The role of the 1000µF capacitor in series with the speaker

Adding a bypass capacitor for noise reduction

Step-by-step breadboard wiring and testing with a speaker

🎥 By the end of the video, you’ll have a working DIY amplifier that can drive a small speaker and give clear, amplified sound.

This project is organized under IEEE SSCS Kerala Chapter as part of our student electronics workshop.
