These LEDs can be made with any LED that needs less than 5 volts to operate and they are really useful when you want to add an LED to a project and don't have a protoboard or want the LED to be right on the Arduinoo.

Step 1: WHat you`ll need

for this project you will need;

  - Any LED that needs less than 5 Volts.
  - The correct resistor for that LED. You can easily calculate it here.
