Steps of Developing the Motor Library

Version 01:

Created two separate functions for testing:

One function to turn the fan motor on or off
Another function to set the motor speed

Version 02:

Combined both actions into a single function and tested the new approach.

Version 03:

Updated the speed control to use a percentage value.
The function now converts the percentage to a value between 0 and 1023 using PWM for smoother speed control.

Version 04:

The previous function, updated to incorporate direction.
