Introduction
On the 7-Color Auto-flash LED module, the LED can automatically flash built-in colors after power on. It can be used to make quite fascinating light effects.
Components
– 1 * Raspberry Pi
– 1 * Breadboard
– 1 * Network cable (or USB wireless network adapter)
– 1 * 7-color auto-flash LED module
– 1 * 3-Pin anti-reverse cable
Experimental Principle
When it is power on, the 7-color auto-flash LED will flash built-in colors.

Experimental Procedures
Build the circuit
| Raspberry Pi | Auto-flash LED Module |
| GND | GND |
| 5V | VCC |
Note:There are two “GND” pins on the module. You only need to connect one of them.
Now, you can see the 7-color auto-flash LED flashing seven colors.
