Task $1-$ Consider the digital clock project I shared with you and create a clock that shows Hours, Minutes, and Seconds. You need to change the display with a $6-$digit Maltiplexd $7-$Segment Display$($ in Proteus, the component name is $7$SEG$-$MPX$6-$CA$).$ Also, we need two new push buttons for setting the second.

Task $2-$ Alarm Clock

Consider the digital clock project I shared with you and create an alarm clock. You need to add a new push button, namely AlarmSet, to the system. if the AlarmSet is not pressed, the clock displays the Hour and Minutes on the $7-$segment. If the AlarmSet is pressed, the display shows the set alarm$($ by default it is $06$:$30)$ and the user can change it by the HourUp, HourDown, MinUp, and MinDown push buttons. The new value for the alarm should be saved in the system and it should be displayed the next time the user presses the AlarmSet button$).$

When the current time equals the alarm time, the system should send a square wave at $100$ Hz on p$3\mathrm{.}7$ for $60$ seconds. A square wave can be generated by setting and clearing a pin port with a delay.
