4) You have been contracted by a family to automate their home using your understanding on electronic circuits.
a) The initial project you work on is a gate automation system that causes the garage door
to open when a car is approaching. You have a proximity sensor that can detect an
approaching vehicle and send a HIGH signal to a motor that lifts the gate. Is it necessary
to use a microcontroller in this system? In not more than 10 lines explain your answer.

b) After using the system for a while, the family decides that the gate opens too slowly
and they want you to modify the system such that the speed at which the gate opens is
calculated based on the speed of the approaching vehicle. In this situation, would you
use a microcontroller? In not more than 10 lines, explain your answer. (10 marks)​
