LED sensor

 

This is the expected output on what it should look like when you have connected everything together as you can see by the image that I have provided we need 3 things that need to be connected to the board 

- Arduino 

- breadboard 

- 3 breadboard wires 

RGB values represent colors in the RGB color model, which is an additive color model in which red, green, and blue light are combined in various ways to reproduce a broad array of colors. Each color component (red, green, and blue) is represented by an 8-bit integer, ranging from 0 to 255. This means that there are 256 possible intensity levels for each color component.

As you can see by the example to the left the black wire is connected to the ground (GND). The white wire is connected to the output which is (A0). The red wire is connected to the power which is (5V). After setting it up you can then control the speed of the light by the potentiometer by twisting it left and right. You will see the expected output number on a new window which is normally called COM.
