Check out this great video from YouTube user Circuit Basics. If you’re new to audio electronics, one of the best projects to build is an audio amplifier with the famous LM386 Audio Amplifier Integrated Circuit. In this video tutorial, he will go step-by-step through the breadboarding process to eventually testing his custom LM386 circuit.
A companion article to this video can be found here, http://www.circuitbasics.com/build-a-great-sounding-audio-amplifier-with-bass-boost-from-the-lm386/, with loads of details that will help you tweak your circuit for optimal sound quality and performance.
NOTE: As you can see in this video, there are a lot of issues that can occur when you use small breadboards. Jumper wires and cables can clutter up your work area and get in your way when you’re experimenting. It’s also common for long -lead resistors and capacitors to create short circuits when bending them out of the way. Your best course of action is to plan your breadboard projects in advance, have a set of solid core wires of varying lengths, and test often during the process.
Until next time, enjoy building your LM386 circuits!
