Reference
This reference guide outlines techniques for controlling LEDs using digital and analog signals, detailing how signal levels affect LED brightness, along with descriptions of communication protocols, APIs, and libraries for efficient LED management.
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.
Other Supplementary Information
-
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.
