https://youtu.be/81zNcctopBI What was the first electronic component you played with? It was probably a LED. They’re fun to blink in patterns or learn to fade. Most projects (and products) use them for useful indicators. LEDs add magic to every electronics project. Often not understand is what else you need to make that LED work correctly. Learn what current limiting resistors do for LEDs and watch what happens when you don’t use one. The most common…
