Intro: 2 Minute Spectrum Generator
In making this circuit you will learn how to use the arduino random number function and how to create different colors on an RGB LED.
This is a real simple plug and play circuit where the RGB module plugs straight into the arduino, pin 8 is permanently low making it effectively GND pins 9,10,11 are analog outputs whose intensity changes the intensity of the three colours in the LED in the following manner
Pin 9 is Red
Pin 10 is Green
Pin 11 is Blue
- Arduino Uno
- RGB module
