Introduction: Make Your Own LED Battery Level Indicator

About: Awesome Electronics Tutorials, Projects and How To´s

In this project I will show you how we can use the classic LM3914 IC to create an LED Battery Level Indicator. Along the way I will show you how the IC works and explain why it is not the most precise circuit for a Li-Ion battery pack. And at the end I will show you how I created my own, more precise Battery Level Indicator circuit with a couple of simple components. Let's get started!

Step 1: Watch the Video!

The video gives you all the information you need to create your own Battery Level Indicator. During the next steps though I will present you some additional information.

Step 2: Order Your Components!

Step 3: Create the Circuit!

Here you can find the schematic as well as pictures of my finished perfboard circuit. Feel free to use them as a reference to create your own circuit.

Step 4: Success!

You did it! You just created your own LED Battery Level Indicator!
