LED ANODE CATHODE ARDUINO CODE

You can glow an individual color or a combination of the three colors. In the loop() function, turn on the specific color by uncommenting the code. In the setup() function, set all the pins as OUTPUT because Arduino will use this pin to send voltage to the RGB LED pins in order to turn on the specific color.

Circuit diagram of common Anode RGB LED with Arduino Arduino code for common Anode RGB LED with Arduino int red=3 Ĭircuit diagram of common Cathode RGB LED with Arduino Arduino code for common Cathode RGB LED with Arduino int red=3 Ĭreate variables for defining the pins of Arduino UNO where you have connected the pins of RGB LED. It will also work in the same manner as that of the common anode RGB LED.īy directly applying a voltage to both the types of LED you can get the RED color, BLUE color, GREEN color, a combination of RED and BLUE color, a combination of RED and GREEN color, a combination of BLUE and GREEN color, and a combination of all the three colors. Then to light up the RED color, connect the RED color terminal to the positive terminal of the power source. To light up a common cathode RGB LED, you have to connect its common terminal to the negative terminal of the power source. You can also light up two or all three colors simultaneously, then you will get different color combinations. Then to light up the RED color, connect the RED color terminal to the negative terminal of the power source. To light up a common anode RGB LED, you have to connect its common terminal to the positive terminal of the power source.

Operating temperature: -25 to 85 degree Celsius.

Luminous Intensity: RED color – 800mcd, GREEN color – 4000mcd, BLUE color – 900mcd.Reverse current(at 5V): RED color – 10uA, GREEN color – 10uA, BLUE color – 10uA.Forward current: RED color – 20mA, GREEN color – 20mA, BLUE color – 20mA.

Forward voltage: RED color – 1.8 to 2.2 V, GREEN color – 3.0 to 3.4 V, BLUE color – 3.0 to 3.4 V.We call it a common cathode RGB LED because in this type of LED, the anode terminal of all three LEDs is shorted internally and connected to one terminal and that terminal is known as a common anode terminal. On the other hand, a common cathode RGB LED also consists of four terminals but in this type of RGB LED one terminal is for the common cathode, one is for the RED LED anode terminal, one is for the GREEN LED anode terminal and the last one is for the BLUE LED anode terminal.

We call it a common anode RGB LED because in this type of RGB LED, the anode terminal of all three LEDs is shorted internally and connected to one terminal and that terminal is known as a common anode terminal. A common anode RGB LED consists of four terminals out of which one is for the common anode, one is for the RED LED cathode terminal, one is for the GREEN LED cathode terminal, and the last one is for the BLUE LED cathode terminal. One is a common anode RGB LED and the other is a common cathode RGB LED. The RGB LED that we gonna discuss in this article is non-programmable and it is of two types. One for the RED color, one for the GREEN color, and one for the BLUE color. In other words, it’s a single LED that contains three LEDs inside it. The RGB LED is a type of LED that can produce three main colors that are RED, GREEN, and BLUE.
