Project 1: Light

Welcome to your first SparkFun Inventor’s Kit project. Each project is broken up into several circuits, each designed to help you learn about new technologies and concepts. The knowledge gained from each circuit will play a part in building each project. This first project will set the foundation for the rest of the projects in the guide and will aid in helping you understand the basic fundamentals of circuit building and electricity!

In Project 1, you will learn about light-emitting diodes (LEDs), resistors, inputs and sensors — using all of those technologies to build and program your own multicolored night-light! The night-light uses a sensor to turn on an RGB (Red, Green, Blue) LED when it gets dark, and you will be able to change the color using an input knob.
