2.1CIRCUITDIAGRAM

In this circuit diagram, the input device sends instructions or commands to the Arduino microcontroller. The microcontroller processes the input and sends output signals to the motor driver,whichcontrolsthemovementsofthestepperandservomotors.

The stepper motors are used to move the drawing surface in a precise and controlled manner, while the servo motor is used to adjust the position of the penholdertocreatethedesiredshape or line. The pen holder holds the pen or other drawing tool and moves it across the drawing surfacetocreatethedrawing.

The motor driver receives signals from the microcontroller and provides the appropriate power and control signals to the motors. The pen holder and drawing surface can be connected to the stepperandservomotorsthroughbelts,gears,orothermechanicalmechanisms.
