Exercise 2

Task

Create a program such that the LED brightness gradually increases from 0 to 255, and then goes abruptly to 0.

Further, modify your program above to decrease the brightness gradually from 255 to 0 instead of an abrupt change.

Hints

• Use pin 11. If you are already having the LED connected to pin 11, you need not change any connection. Why can’t you use pin 13?

• You will have to use a for loop. Lookup for in https://www.arduino.cc/en/Reference

• The delay should be around 5-10 milliseconds.
