Question

Show the circuit diagram to interface one switch to PB0 and four LEDs to PA3-PA0. The four LEDs will display a number from 0 to 15 in binary. Write software that initializes the ports. In the body of the main program, increment the number every time the switch is pressed and released. Wait at least 10 ms in between reading the switch. Once the number gets to 15, do not increment it any more.
