On tutorial we will going to make a chasing LED, we will going to wire 10 LED to make an LED chase effect, similar to that used on the bikes and cars knight riders.
Electronic parts required
Arduino UNO/MEGA/MINI/NANO
10x LED
10x 220 Ohms Resistors
Jumper wires
Solder-less Breadboard
Wiring the LED to Arduino
Arduino Sketch

LED Running Light or Chasing Light Effect
code does not work when I compile, something is missing.
