SKU_BOS0017_LED_Module_R_G

Introduction

LED is a method of converting electronic energy into the lights. These BOSON LEDs have three colors: red, green, and blue, and support brightness adjustment. LED is now widely used in LED display, indicator, traffic lights, car lights, decorative lights, etc. They can be combined with output modules of all sorts to realize various functions.

Board Overview

Label	Description
GND	Power -
VCC	Power +
SIGNAL	Digital signal line

Usage Description

Use digital signal to control the LED module, input high level to turn on the LED, low level to turn it off.
Use analog signal to control the fan module, the larger the input signal, the brighter the LED and vice versa.

Principle

The LED is mainly composed of epoxy resins package housing, LED chip, reflective cavity, Cathode and Anode rods, leads, etc., shown as below. You can input high level to the LED to turn it on, low to turn it off. Also, you can use analog signal to control it, the larger the input signal, the brighter the LED.

Application

Light Emitting House

Description: Control the LED by a button module. Press down the button to switch on the LED, release, it goes off.
