LedcSetup(RED_channel, PulseWM_Frequency, PulseWM_resolution) #define PulseWM_resolution 8 // 8 bit resolution #define PulseWM_Frequency 5000 // PulseWM frequency
Step 6 − Upload the program to ESP32 by pressing the right arrow near the tick sign. Write the C program and compile it using the tick sign.

Step 4 − Download Arduino IDE if it is not installed on the Computer and set it ups. Now connect the resistor pins to ESP32 pins (D21, D19, D18 ).
Connect the longest leg of RGB LED to the blue rail directly and the other lines to resistors. Step 2 − Attach the breadboard negative rail to the ESP32’s GND. Step 1 − Connect the ESP32 microcontroller to the breadboard. Then write the C program using Arduino IDE. So, first, make the circuit as shown in fig 1. Arduino IDE is then needed to write the C program, compile it and then push it into ESP32 for its execution. Example 1: Using an RGB led with ESP32įirst the ciruit is made using breadboard, ESP32, one RGB LED, 3 resistors and some male-to-male wires. The first one is for red, the third one for green, and the fourth one for blue. It has 4 pins and the longest one (2nd in number) is –ve. RGB led is an LED that can show the mix of RGB colors and can produce shades.

In example 2, the Wokwi simulator is used with Arduino microcontroller and an RGB led with red, green, and blue single colored leds. In example 1, the actual circuit using a breadboard, ESP32, RGB LED, resistors, and wires is made and the components are controlled using the C program made using the Arduino IDE. In this article, using two different examples, the way to use the RGB led is given. However, to get real results, using the circuit components and making the actual circuit is important. There are some simulators available to make the beginner of IOT learn such concepts without even having the IOT devices available. Then it is important to manage that circuit using a program. I'm sure there are also other implementations.To learn about RGB led and the difference between single-color LEDs, it is important to make a circuit using a microcontroller such as ESP32 or Arduino and RGB led. I have not tested it, so I cannot say, if it really works correctly, but you should give it a try.

I think there are suitable implementations, that can be found on the web.Ī quick search gave me this code from github gist. In this forum thread there is a brief discussion about that, though it leaves you with the implementation yourself. You can write your own function to convert 'RGB' values to 'HSV' then use it to access the 'hue' and 'Saturation' values for the targeted 'RGB' Color, create a new 'HSV' Color with it and the new 'Brightness' and use it to set the 'RGB' values for the FastLED library. This is not an issue, if you have enough memory or few enough LEDs to control.Ģ.
This is relatively easy, but you effectively need double the memory for storing the color values. You can just define an extra LEDs array with HSV colors and synchronize both arrays to contain the same data (everytime you want to change a color, you would set a 'HSV' color in the second array, convert that array to 'RGB' by using 'CRGB(hsv_leds)' and save that in the first array, which get's used by the FastLED library). So you cannot simply get the 'hue' and Saturation from an 'RGB' Color with this library.ġ. The FastLED library can convert 'HSV' Colors to 'RGB' Colors but not the other way round. There you will find the Hue value that gets changed but it is the same principle as 'brightness'. You can see the 'HSV' usage example within the 'Cylon' example on the FastLED library. This assignment uses an implicit conversion, that is defined in the library. Note that 'leds' is still defined as 'CRGB', not as 'HSV'. While 'Color' and Saturation' remain the same (to keep the same color), you can change the 'Brightness' directly on the third parameter. leds = HSV(color, saturation, brightness) Just set the LEDs color to a HSV value and change it's V value. You can (however) do this by using the HSV color model. There is no dedicated function to adjust brightness.
