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 A0 and A1. 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 A1 A0

0 0 0

1 0 1

2 1 1

3 1 1(open the lock)

2. An automatic door at a store has a sensor in front (A0) and behind (A1). The door opens (B0=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.
