Extend your circuit to include a potentiometer, button and LED and implement the following functionality:

BTN toggle

$-$ LED and Motor both on and off.

PTM dial controls motor speed and direction

$-$ middle position: motor is at rest.

$-$ dial left: motor spins left

$-$ dial right: motor spins right

$-$ moving the dial away from the center position in either way speeds up the motor

$-$ use the map$()$ function to assign the motor speed from $0$ to $255$ according to the dial position
