Flashing LED

This simple flashing LED (Light Emitting Diode) circuit is based on the ARDX 01 circuit from Oomlout.  It serves as an excellent introduction to Arduino programming.  Start by gathering your parts together:

Step 1:  Set up the circuit

Upload the circuit and enjoy the fruits of your labour.

Step 3: Extensions

  • Lengthen the time between flashes.
  • Shorten the time between flashes
  • Improve the program so you have long and short flashes.
  • Extend the program further so it produces an SOS signal.
