(4) x M-M wires (Male to Male jumper wires)ĭownload and open the Code Zip file and follow the directory path:Ĭode > Lesson 4 RGB LED > RGB_LED > Click on the RGB_LED Arduino File and it should automatically open the Arduino IDE interface with the code for the lesson. By doing this we will cycle through most of the color that can be achieved. In our sketch, we will start with the LED in the Red color state, then fade to Green, then fade to Blue and finally back to the Red color. They come mostly in 2 versions: Common Anode or Common Cathode.Ĭommon Anode uses 5V on the common pin, while Common Cathode connects to ground.Īs with any LED, we need to connect some resistors inline (3 total) so we can limit the current being drawn. Using Common Cathode and Common Anode RGB LED with Arduino - Hackster.io Common Cathode RGB LED arduino Circuit Technology Tutorials Arduino Working with.

Since they are like 3 regular LEDs in one, how to use and connect them is not much different. In this article and video I have covered about interfacing of RGB common cathode LED using pin outs of Arduino Uno. Orient it in the breadboard with the red leg on the left, and power leg second from the left. Project Steps Plug in the RGB LED Grab all the parts, and begin by plugging the Common Anode RGB LED into your breadboard. The anode always connects to the positive side of the circuit and connecting each cathode to the negative side of the circuit allows current to flow through that specific LED. to you For RGB LED with common Anode, you need to: Connect the common pin to 3. How to fade between colors with the Common Anode RGB LED, included in Maker Shed’s Ultimate Arduino Microcontroller Pack. A common-anode RGB LED has four leads: one anode, and one cathode for each color. RGB LEDs are a fun and easy way to add some color to your projects. Now its time to write the code to control our Arduino RGB LED strip. Taken from page 46 of the ELEGOO Super Starter Manual.
