The Bluetooth Controlled CNC Drawing Machine is a compact, computer-controlled device that can create precise drawings, patterns, and text on paper or other flat surfaces. It uses Bluetooth connectivity to receive commands from a smartphone or computer, making it wireless and easy to operate.

This project demonstrates the integration of CNC technology with wireless communication, allowing users to control the drawing process remotely. It’s ideal for students, hobbyists, and designers who want to explore automation in art and engineering.

Parts Used:

1. Microcontroller Board (e.g., Arduino UNO) – controls the motors and processes commands
2. Bluetooth Module (e.g., HC-05) – enables wireless communication
3. Stepper Motors & Drivers – control precise X and Y axis movement
4. Servo Motor – lifts and places the pen
5. Frame & Guide Rails – provide structure and smooth motion
6. Pen Holder – holds drawing instruments
7. Power Supply – provides required voltage and current
