Write a program for speed and direction control of the DC$-$Motor based on the states of the three switches and one potentiometer.

$($Note $1$: Draw the circuit which contains a L$293$D driver with DC$-$Motor$).$

$($Note $2$: Use PWM module to control in speed and direction of the DC$-$motor$).$

Note $3$: SW$1$: B$0===>$ FORWORD

SW$2$: $B1===>$ REVERSE

SW$3$: B$2===>$ STOP

Potentiometer: $A0===>$ CHANGE SPEED
