The Rolling Cloud is a cloud light that can help you roll. The Material that we need have:

1. a stack of cotton that can cover your whole Arduino.

2. Arduino board.

3. breadboard.

4. five electric line

5. two resistance

6. two led light(green)

Step 1: Step 1

First, connect circuit properly like the picture.

Step 2: Step 2

Seam the cotton around Arduino and breadboard.

Step 3: Step 3

Sent the code to Arduino. (under)
