Varier l'intensité de lumière d'un module LED RGB avec Arduino
To connect RGB LED to Arduino, we need to use current-limiting resistors. This can make the wiring complex. Fortunately, we can use the RGB LED module, which already has built-in current-limiting resistors. RGB LED Module also includes four pins: Common (Cathode-) pin: needs to be connected to GND (0V) R (red): pin is used to control red
RGB Led with Arduino UNO Example TECHATRONIC
Connecting an RGB LED with an Arduino is very simple. Here I will show you how to connect a common cathode RGB LED to an Arduino Uno Board. From the above image, you can see that I connect the common cathode pin to the ground pin and connect the other three pins to the Arduino PWM output pin - 3, 5, and 6 using three 220 Ohm (Ω) resistors..

New Arrival RGB 3Color LED Module for Arduino
We use common cathode RGB led. Connect the cathode of the RGB LED which is a longer leg to the Ground (GND) of Arduino and the other three legs to pin 3, 5 and 6 of Arduino along with a 220 ohms resistor with each leg. The resistor will prevent the current flow and LED bursting. Refer to the below circuit diagram.
