Explore the fundamentals of circuit building and electricity in this 30-minute tutorial from SparkFun Electronics' SIK v4.1 Project 1: Light. Learn about light-emitting diodes (LEDs), resistors, inputs, and sensors while building a programmable multicolored night-light. Begin by downloading necessary drivers, then progress through four circuits, each introducing new concepts and technologies. Gain hands-on experience with RGB LEDs, sensors, and input knobs to create a night-light that automatically activates in darkness and allows color customization. Access the online HookUp Guide for detailed instructions and follow along with the video's time-stamped sections covering driver installation and each circuit build.
