This example uses 2 LEDs and a switch to make an ON/OFF door lock. When the RED LED is ON then the door lock is closed. When you press the BUTTON, door will open and the RED LED will be off and the GREEN LED will be ON.

Parts List

You will need the following parts:

  • 1x arduino uno

  • 1x arduino uno USB Cable

  • 1x Breadboard

  • 5x Jumper Wire

  • 1x Red LED

  • 1x Green LED

  • 1x Push button switch

  • 3x Resistors

Wiring it up

Ensure that the LEDs are the right way around, with the longer positive leads (anodes) to the left.
