Assignment 4: Changing notes

In this assignment I decided make it so that the note being played is changed by the button pressed. Button A decreases the note and a red led lights up when pressed. Button B does nothing. Button A+B sets it back to the lowest note it starts at and both green and red led's light up. The Button added in Pin 1 increases the note and a green led lights up. And the most it can be increased is 7 times and the number that its on is displayed on the micro bit.
