• ^{L293D Motor Driver IC: To drive the DC motor.}
• ^{DC Motor: To be controlled.}
• ^{LCD Display (16x2): To show the motor status.}
• ^{Potentiometer: To control motor speed.}

^Explanation

1. ^{Motor Control:}

   • ^{L293D Motor Driver:}
     • ^{Pins in1 and in2 are used to control the direction.}
     • ^{Pin enA is used to control speed using PWM.}
   • ^{The motor is set to rotate in a specific direction (in1 HIGH, in2 LOW) by default.}

2. ^{Speed Control:}

   • ^{A potentiometer is used to control the speed.}
   • ^{The analogRead(potPin) reads the value from the potentiometer, and map() scales this to a range suitable for PWM (0–255).}
   • ^{The analogWrite(enA, motorSpeed) function sets the PWM value to control motor speed.}

3. ^{LCD Display:}

   • ^{LiquidCrystal Library: Used to control the LCD.}
   • ^{The LCD displays:}
     • ^{The current speed of the motor as a percentage (0-100%).}
     • ^{The direction of rotation (Clockwise in this example).}

4. ^{Control Logic:}

   • ^{The motor speed is adjustable using the potentiometer.}
   • ^{The direction is currently set to clockwise (in1 HIGH, in2 LOW). This can be changed to counterclockwise by swapping these pin states (in1 LOW, in2 HIGH).}
