Along the way you will learn how to wire up solar cells and how they are usually wired up in a commercial solar panel. At the end we will then evaluate whether the DIY version is cheaper to produce.

Part 1: https://youtu.be/jX1GaPgSheI Facebook: https://www.facebook.com/greatscottlab Twitter: https://twitter.com/GreatScottLab Support me for more videos: https://www.patreon.com/GreatScott?ty=h More information on Instructables: http://www.instructables.com/id/Make-your-own-SIMPLE-5x5x5-RGB-LED-Cube/ In this 2 part video series I will show you how to build a simpler version of a 5x5x5 RGB LED Cube. The driver circuit only consists of an Arduino Nano and the programming is rather simple due to the FastLED library.

At the end I will then compare both heart rate monitors in order to find out whether my smartwatch still works fine. Let's get started!
