Write a C program Using: ATMEL STUDIO.

with an Arduino UNO, a breadboard, and an LED.

Create a C program which will do the following:

Generate a PWM signal on an OCR pin and use this pin to drive an LED.

Gradually change the duty cycle of the LED so that the brightness increases from 0% to 100% and then back down to 0% and repeats.

Bonus (10 points):

Using an RGB LED, setup three separate PWM outputs on the AVR and connect one to each colored LED.

Continuously change the duty cycles of the three PWM signals at different rates, so that the RGB LED continuously is a different color.
