Exercises

Use RIMS simulator to create and run a program as a solution to each of the two exercises below: NOTE: This homework is to be coded in C language with while loops to wait for changes.

Maybe you do not have a perfect solution. Do the best you can and submit your work to show you have done diligence on these exercises.

$1.$ A lock has two switches. These are A$0$ and A$1.$ Once the proper sequence is followed, the lock will open. Write C code for the lock using while loops to wait.

Start at State $0,$ waiting for State $1$ to become true, pseudocode is: while $(!($State $1))$ then wait for the correct next state condition to occur

State A$1$ A$0000101211$

$310$ open the lock

$2.$ An automatic door at a store has a sensor in front $($A$0)$ and behind $($A$1).$ The

door opens $($B$0=1)$ when a person approaches from the front, and stays open as

long as a person is detected in front or behind. If the door is closed and a person

approaches from the behind, the door does not open. If the door is closed and a

person approaches from the front but a person is also detected behind, the door

does not open, to prevent hitting the person that is behind. Show a description of the sequence of events and the C code for the solution.
