RGB LED Circle Board, 5050/12V
For RGB LED with common Anode, you need to: Connect the common pin to 3.3V of Arduino. Change R, G and B values in analogWrite () function to 255 - R, 255 - G, and 255 - B, respectively. A sequences of RCB LED connected together creates the RGB LED Strip. LED strip can be categorized in to the addressable LED strip and non-addressable LED Strip.
ALITOVE Addressable RGB LED Strip for PC, 5V WS2812B Rainbow Digital Light Strip for ASUS Aura
There are two ways to go about lighting an RGB LED module on any Arduino board. The usual method is to use the Arduino's analog pins to send PWM signals to the module. This lets you mix each color, giving you full control over the RGB LED. Meanwhile, the other (digital) option is to use pins 11, 12, 13, and GND by attaching the module to the.

How to drive RGB LEDs with ESP32 & ESP8266 NotEnoughTech
The best way to distinguish between a common cathode and common anode RGB LEDs is using a multimeter. Put you multimeter is in continuity mode. Place the red multimeter tip on the longest LED lead. Then, place the black tip on one of the other leads. If the LED lights up, this means you have a common anode LED.
Square RGB LED board Custom LED iPixel LED
Powering the WS2812B LED Strip. The LED strip should be powered using a 5V power source. At 5V, each LED draws about 50mA, when set to its full brightness. This means that for every 30 LEDs, the strip may draw as much as 1.5 A. Make sure you select a power source that matches the strip's needs.
Matek RGB LED Board, 5050/16V
Breadboard Layout. The RGB LED has four leads. There is one lead going to the positive connection of each of the single LEDs within the package and a single lead that is connected to all three negative sides of the LEDs. The common negative connection of the LED package is the second pin from the flat side of the LED package.

Common Cathode RGB LED. In a common cathode RGB LED, the cathode of the internal LEDs are all connected to the external cathode lead. To control each color, you need to apply a HIGH signal or VCC to the red, green, and blue leads and connect the anode lead to the negative terminal of the power supply. Common Cathode RGB LED Pinout.

Arduino and RGB LED Circuit Schematics. The cathode will be connected to the ground and the 3 anodes will be connected through 220 Ohms resistors to 3 digital pins on the Arduino Board that can provide PWM signal. We will use PWM for simulating analog output which will provide different voltage levels to the LEDs so we can get the desired colors.
