7.8.2 Lab 7b: Control RGB-LED

In this experiment you shall create a program that can control the intensity of each (of the three) LED.

Select which color to adjust with a push-button (rotate around the three main colors, red, blue, green,

at each press) and set intensity level with the trimming potentiometer.

Base the program on the knowledge developed in previous PWM-related experiments (for example

Lab 6d). Below is the breadboard design that can be used.
