In this video we show you how to build a simple project using a servo and arduino. The project reads a light brightness value, and then creates a visual display with an arrow that points out brightness, ranging from moonlight to full sun. This requires the use of Algebra, and the equation of a line.

You can get the kit I am using for this series at the following link:

Also, you can get nicer servos than the ones in the Elegoo kit here. These are the good ones I use in most of my projects.
