In this tutorial, you will learn about Arduino RGB led interfacing. The RGB led consists of three different led’s, from the name you can guess that these led’s are red, green and blue. We can obtain many other colors by mixing up these colors. To mix colours we are going to use 3 buttons to choose the desired colour (R,G,B) and potmeter to control the instance of the colours. You will be able at the end of this turtoial to understand the electrical schema and the source code and how Arduino's work. In addition if you choose for the extra service, you will be able to control your light and mix colours by seding messages to the led, Imagine: You can type to your led " I want RED" and your led will understand you!!!
