Pen Plotter Project

A precise and elegant system for automated drawing using Arduino control.

Features

High-Precision Movement

DC motors with encoders ensure accurate X/Y/Z-axis positioning.

Interactive GUI

Built with Python and Tkinter for shape design and command execution.

3D-Printed Frame

Customizable modular structure for easy assembly.

Automated Workflow

Converts digital designs into physical drawings via Arduino.

Circuit Diagram

The report mentions Arduino Mega and stepper motors, but the BOM specifies Arduino Uno and DC motors.

Component	Quantity	Description
416 DC Motor + Encoder	3	Controls X/Y/Z-axis movement
Arduino Uno R3	1	Main microcontroller
9V Battery	1	Power supply

Assemble the 3D-printed frame
Mount the motors and attach the pen mechanism
Wire components as per the circuit diagram

For NixOS Users:

nix-shell

For Non-NixOS Users:

python3 -m venv venv

                                source venv/bin/activate

                                pip install -r requirements.txt 

                                # install the `imagemagick` package as well if you wanna use the manual method, it's available in most package managers... or compile it from here.

Usage

Manual Drawing via GUI

python3 manual.py /path/to/image

Controls:

Middle Click: Show/hide image
Right Click: Draw connected polygons
Left Click: Start new polygon
Close Window: Saves drawing

Automatic Conversion

python3 main.py criam.jpg criam

Converts 'criam.jpg' to sketch code in ./criam/criam.ino

For complex images, use online AI tools first!

Upload to Arduino

arduino-cli board list

alias ards="sudo arduino-cli compile --fqbn arduino:avr:mega ./ 

sudo arduino-cli upload -p /dev/ttyACM0 --fqbn arduino:avr:mega ./"

Or use Arduino IDE for uploading

Drawing Results

Examples include faces, cars, landscapes, and geometric shapes
