What’s in an LED

LED,_5mm,_green_(en).svgThat kinda stuff…. what do we care about?

  1. LEDs are awesome, they are the most fun electrical component in the world.
  2. They can be really bright
  3. They are super easy to burn out.
  4. ALWAYS use a resistor with these bad boys. Unless you don’t want to.
  5. A simple circuit looks like this:simple-circuit.png
  6. So whats that? Power goes to a switch, which goes to an LED (which shines cause they are shiny) which goes to a resistor which restricts the current, more on that in the resistor section) and that goes back to the battery. Build this and super impress your friends.
  7. What’s needed: 100Ohm resistor, switch, wire, LED, prototyping board, 5 mins and a battery.

Enjoy 🙂
