Introduction: Flowing LED Light Cloud

-This instructable is originated from

I replaced:

1. The 8 lightbulb into 6 lightbulb

2. The color ( Red, red, yellow, green, red, yellow, green, red) into (red, red, yellow, blue, blue, red)


The principle of this experiment just simply to make the six LED lights turn on. The six LEDs are linked to pin 2-pin 7 respectively. Set them as High stage and the corresponding LED on the pins will light up. Control the time of every LED brightening and you may see flowing LED lights.

Step 1: Materials

1. lightbulb*6

a. blue*2

b. red*3

c. yellow

2. Arduino Leonardo board*1

3. USB cable *1

4. Breadboard*1

5. Jumper wires*8

6. Resistor (220Ω) * 6

Step 2: Build Up the Circuit As the Picture Shown

Step 3: Download the Code
