Make Your Own Power Meter/Logger

In this project I will show you how I combined an Arduino, an INA219 power monitor IC, an OLED LCD and a Micro SD Card PCB in order to create a power meter/logger that has more functions than the popular USB Power Meter. Let’s get started!

Step 1: Watch the Video!Make Your Own Power Meter-Logger

The video gives you a good overview on how to create your own power meter. In the next steps though I will present you some additional information to make this project even simpler.

Step 2: Order Your Parts!

Here you can find a parts list with example seller for the portable version of this project.
