Resources and Going Further
You've made it! You know, like, almost everything... about LEDs. Now go forth and put LEDs on whatever you please! And now... a dramatic reenactment of an LED without a current limiting resistor being over powered and burning itself out:
Yeah... it's not spectacular.

Light
Light is a useful tool for the electrical engineer. Understanding how light relates to electronics is a fundamental skill for many projects.
IR Communication
This tutorial explains how common infrared (IR) communication works, as well as shows you how to set up a simple IR transmitter and receiver with an Arduino.
How LEDs are Made
We take a tour of a LED manufacturer and learn how PTH 5mm LEDs are made for SparkFun.

This guide contains all the information you will need to explore the twelve circuits of the SparkFun Inventors Kit for micro:bit.
Mean Well LED Switching Power Supply Hookup Guide
In this tutorial, we will be connecting a Mean Well LED switching power supply to an addressable LED strip controlled by an Arduino.
Basic Character LCD Hookup Guide
Liquid crystal displays (LCDs) are a great way to output a string of words or sensor data to a display for visual feedback. In this tutorial, we'll learn about LCDs, how to print a string of words to a 16x2 basic character LCD and create custom characters.
