A DC motor is controlled by two buttons, namely B$1($for start$)$ and B$2($for stop$).$ When

the B$1$ button is pressed, the motor will start rotating to the right $($O$1$ output will be

active$)$ and will continue this movement during $20$ seconds. Then, it will rotate to the left

$($O$2$ output will be active$)$ for $20$ seconds. This operation will continue until the B$2$ button

is pressed. When the B$2$ button is pressed, the motor will stop after $5$ seconds and will

not accept the restart command $($via the B$1$ button$)$ for the next $10$ seconds. At the end of

these $10$ seconds, the system will return to the initial state and wait for the B$1$ button to

be pressed again.
