Problem 1 [16 points]\ Design a 16F84A MCU-Based system that would detect the status of two push buttons\ (PB1 and

PB2

) and would accordingly turn ON/OFF two LEDs (LED1 & LED2) and one\ DC motor as per the following design requirements:\ i. All devices shall be interfaced with PORTB pins. Other ports are not\ allowed to be used.\ ii.

PB1

shall be interfaced using a pull up resistor, while

PB2

shall be\ interfaced through a pull down resistor.\ iii. LED1 shall be interfaced to the chosen PORTB pin directly through its\ Anode, while LED2 shall be interfaced directly to another pin through its\ cathode.\ iv. The DC Motor requires an external

9V

power source.\ v. All LEDs shall be ON all of the time, they only turn OFF while (PBD) is\ pressed.\ vi. The DC motor shall be OFF all of the time, it only turns

ON

while

PB2

is\ pressed.\ vii. The user shall be able to manually reset the system at any time.
