Objective:

Learn how to control a DC motor using Arduino with PWM (Pulse Width Modulation) for speed control.

Steps to Perform:

1. Look at the Arduino Code in the code editor below
2. Find Line 8: analogWrite(11, 20); - this controls motor speed
3. Click on line 8 and change the value to any number between 0-255
4. Click "Apply Code" button to update the motor speed
5. Click "Start Simulation" to power up and see the motor rotate
6. Observe how the motor shaft rotates at the speed you set
7. Try different values: Higher = faster, Lower = slower, 0 = stopped
8. Click "Stop Simulation" to turn off the motor

Key Concepts:

• DC Motor: Converts electrical energy to mechanical rotation
• PWM Control: Uses analogWrite() to control motor speed (0-255)
• Pin 11: PWM-enabled pin connected to motor driver circuit
• Speed Range: 0 = stopped, 255 = maximum speed
• Editable Code: Modify line 8 directly to change motor behavior
• Motor Driver: Circuit amplifies Arduino signal to drive motor
• Real-time Testing: Edit code and apply changes to see immediate results
