Input: Three Buttons
Servo: Output
LED: Output:
Troubleshooting:
Turning off all the components once the output is set to HIGH
Button Combo Code:
//Make a global variable = 0
//Make if statements with && stating if button is pressed turn global variable to 1
//Make final output to = 3 after all the buttons are pressed.
