queue ticket calling system using STM$32$ development board. A push button is used as the input to the embedded system to increase the number of the queue ticket for next customer. Common$-$anode $7-$segments are used to display the current ticket number.Assuming that the push button is normally open, sketch the schematic how you interface the push button to trigger an active$-$high signal to the embedded system every time it is pressed$($ii$)$ Sketch the schematic to illustrate how you interface ONE $(1)$ of the common$-$anode $7-$segments to pin D$2$ till D$8$ in the development board. $[5$ marks$]($iii$)$ Explain how to connect the rest of the $7-$segments using the same data bus $($D$2-$ D$8)$ as in Ql$($a$)($ii$).$
