-In order to allow for the LED that is connected to the circuit to be turned on and off through the code of the program for ptb0 we need to change the mode of the LED to output. We do this through the line of code "pinMode (LED, OUTPUT);". The "LED" factor in the parentheses is simply whatever variable name you assigned to the LED when you initialized it.

+In order to allow for the button that is connected to the circuit to be used as an actual input for the code and to power the light through the code of the program for ptb0 we need to ensure that the mode of the pin the button is connected to is set to input.
