Pinout
| Label | Name | Description |
|---|---|---|
| 1 | GND | Power Negative |
| 2 | VCC | Power Positive |
| 3 | SIGNAL | Digital Signal Line |
Usage Description
Control the LED strip by digital signal: input high, LED strip lights up; input low, it turns off.
Control the LED strip by analog signal: the larger the input signal, the brighter the LED strip; the smaller the signal, the dimmer the LED strip.
Principle
This LED Light strip(fixed color) is composed of a series of LEDs. It supports 5V power supply and adopts transistor switch. Input high to turn on LED strip and low to turn off it. The brightness of the strip can be adjusted via the analog signal. The larger the input signal, the brighter the LED strip.
Application
1. Shining Tiara
Description: twine the LED strip around a tiara. When the tilt sensor detected there is a "tilt", the LED strip will light up.
