RGB LED (common anode) A common anode RGB LED is nothing more complicated than three one colour LEDs (one red, one green, and one blue) housed in a single package. The resistors we use here are 100 ohms (Brown Black Brown rings). Step 1: Parts Only a few parts are required. The purpose of the resistors is to limit the amperage in the circuit and hence protect the LED from receiving a too strong current (which could damage the LED). The anode is the positive side of the LED, so having a common anode means you can connect the anode pin to the positive power rail and then switch on the. However, LEDs and LCDs are only capable of displaying those colors individually. These cones are detectors for red, green, and blue color. Arduino RGB LED Colors The human eye has only three cones (most people). This is how we will connect our RGB LED to our Arduino board. The LED shares a common ground, apply 3.3V to 5V to each Anode will light the different colors. It has 3 cathodes (+ pins) that can take different amperages. How to find out Simply check the manual or description of what youve bought. It consists of a RED LED, a Green LED and a Blue LED all within the same component. Depending on your RGB LED, this can be a cathode or an anode. It features four pins, one for each of the three colors (red, green, and blue) and one. This code consists of three numbers between 0 and 255, indicating how much red, green and blue are used to recreate the colour.Ĭheck the following RGB Color picker to see how RGB codes work:Īn RGB LED is a 3-in-1 LED. Our LED is compact and easy to use, measuring just 10mm in diameter. Open Tinkercad in new windowĭid you know that every colour on the screen can be represented using an RGB code (Red, Green, Blue) code. Instead you can use the online Arduino simulator from Tinkercad to recreate the electronic circuit and add the code provided below. You do not need to have access to an Arduino board. In this challenge we will use the Arduino board to control a RGB LED to create a gradient light effect where the LED will fade from red to purple, to blue, to purple and back to red.
