HW-478 HW478 KY-009 3 Colour 5050 RGB SMD LED Board Module

Product details of HW-478 HW478 KY-009 3 Colour 5050 RGB SMD LED Board Module
An RGB LED is a type of LED that can emit three different colors of light: red, green, and blue. The working principle of an RGB LED with Arduino involves using pulse width modulation (PWM) to control the intensity of each color. By adjusting the duty cycle of the PWM signal, the Arduino can change the amount of current flowing through each LED, causing the LED to emit a different color of light. For example, if the duty cycle of the red LED is set to a high value, the LED will emit a bright red light. If the duty cycle of the green LED is set to a low value, the LED will emit a dim green light. By combining the intensities of the three colors, the Arduino can create a wide range of different colors. The Arduino PWM duty cycle value varies between 0 and 255. By assigning a PWM value to any color we can either set it as full bright or turn it off completely. 0 corresponds to LED off and 255 corresponds to full brightness.
