1. Connect a push-button and a 7-segment LED to you Arduino Mega 2560. a. Wire the push button to be active low using the internal pullup resistor. b. Wire the 7-segment to a single GPIO port such that writing an 8 bit value to the port will result in a particular character being displayed on the 7-segment. 2. Write a program to increment your 7-segment display by one character each time the button is pressed. a. The 7-seg initially shows 0. b. Press button once c. The 7-seg shows 1 d. Press button again e. The 7-seg shows 2, and so on. 3. It rolls-over from F back to 0. a. Make sure your program properly denounces the signal such that the display only increments once for each button press. b. The value increments after the finger is taken off the button
