The KY-009 RGB Color LED module is commonly used in a variety of electronic applications, such as: This is a routine to change the color of four LEDs. If you use Arduino to write a program, the Makeblock-Library-master should be invoked to control the Me RGB LED. Serial.println(val) //print current value When the Dupont wire is used to connect the module to the Arduino UNO Baseboard, its SIG pin should be connected to digital port as follows: Guide to programming Arduino programming. Int greenpin = 9 // select the pin for the green LEDĪnalogWrite(redpin, val) //set PWM value for redĪnalogWrite(bluepin, 255 - val) //set PWM value for blueĪnalogWrite(greenpin, 128 - val) //set PWM value for green Int bluepin =10 // select the pin for the blue LED int redpin = 11 //select the pin for the red LED
ARDUINO RGB LED MODULE CODE
The following Arduino code will process through different colors by modifying the PWM value on each of the Red, Green, and Blue primary colors. The unique article identifier refers to a specific instance of the KY-009 RGB Color LED module, which can be used to distinguish it from other similar modules. The module can be connected to an Arduino board or other microcontroller to control the color and brightness of the LED. The KY-009 RGB Color LED module is a simple and low-cost module that consists of an RGB LED, which can produce various colors by mixing red, green, and blue light. You will require the following Hardware Components for the Interfacing of the KY-009 RGB Color LED module with arduino. that will turn on the RGB Led light on adjusted colors. This module is capable of interfacing with popular electronic platforms like Arduino, ESP32, Raspberry Pi, and other microcontrollers. Each color is modified by operating Pulse Width Modulation (PWM). Here you should see the RGB LED flash circularly red, green, and blue first, then red, orange, yellow, green, blue, indigo, and purple.The KY-009 RGB Color LED module emits rays of colors by a mixture of red, green, and blue light. Step 4: Upload the sketch to the SunFounder Uno board Step 2: Program (Please refer to the example code in LEARN -> Get Tutorial on our website) Here we input a value between 0 and 255 to the three pins of the RGB LED to make it display different colors.
WS2801 pixels Led Strip IOS Android, LED Light, LED Controller, RGB. In this experiment, we will also use PWM which, if you’ve followed the lessons thus far, you already have a basic understanding of. Categories > JavaScript simulation of WS2811/WS2812 LED strips commonly used with Arduino. This process is known as additive mixing. However, the brightness is equal to the sum of all brightness, and the more you mix, the brighter the LED is. When superimposing the light emitted by the three primary colors, the colors will be mixed. When the three primary colors are all 255, “LED light” is the brightest. When the three primary colors are all 0, “LED light” is the darkest, that is, it turns off. If you say the color displayed doesn’t completely match a natural color, then it almost certainly cannot be differentiated with the naked eyes.Įach of the three color channels of red, green, and blue has 255 stages of brightness. RGB displays various new colors by changing the three channels and superimposing them, which, according to statistics, can create 16,777,216 different colors. RGB stands for the red, green, and blue color channels and is an industry color standard. In this lesson, you will use PWM to control an RGB LED and cause it to display all kinds of colors.
