# LED Chasing
## What will we do
In this lesson we will add one more LED and create a light chasing effect. We will use 3 of the same color LED’s\*\*.\*\*
The sequence for the code will be as follows
* Turn LED1 ON
* Wait for 0.5 second
* Turn LED1 OFF and LED2 ON
* Wait for 0.5 second
* Turn LED2 OFF and LED3 ON
* Wait for 0.5 second
* Turn LED2 ON and LED3 OFF
* Wait for 0.5 second
* Turn LED2 OFF and LED1 ON
## Parts List
You will need the following parts:
* **1x** arduino uno
* **1x** arduino USB Cable
* **1x** Breadboard
* **3x** Jumper Wire
* **3x** LED (all same colour)
* **3x** Resistor
## **Wiring it up**
Ensure that the LED are the right way around, with the longer positive leads (anodes) to the left.
