Pin Configuration

3D Printing Pen Documentation
Pinout Explanation
The 3D Printing Pen has a total of 6 pins, which are used to connect to a microcontroller or a computer to control the pen's operations. Below is a detailed explanation of each pin:
Pin 1: VCC (positive power supply)
Function: Provides power to the 3D Printing Pen
Voltage: 5V to 12V DC (dependent on the specific pen model)
Connection: Typically connected to the positive voltage rail of a power supply or a battery
Pin 2: GND (ground)
Function: Provides a reference ground connection for the pen
Voltage: 0V
Connection: Typically connected to the negative voltage rail of a power supply or a battery
Pin 3: CLK (clock signal)
Function: Clock signal input for the pen's motor control
Frequency: Typically 16 kHz to 20 kHz (dependent on the specific pen model)
Connection: Connected to a digital output on a microcontroller or a clock signal generator
Pin 4: DIR (direction control)
Function: Controls the direction of the motor (forward or reverse)
Logic Level: TTL (Transistor-Transistor Logic) compatible
Connection: Connected to a digital output on a microcontroller
Pin 5: EN (enable signal)
Function: Enables or disables the motor operation
Logic Level: TTL compatible
Connection: Connected to a digital output on a microcontroller
Pin 6: T (temperature sensor input)
Function: Analog input for the temperature sensor (optional)
Voltage Range: Typically 0V to 3.3V or 0V to 5V (dependent on the specific pen model)
Connection: Connected to an analog input on a microcontroller or a dedicated temperature sensor amplifier
Connection Structure
To connect the 3D Printing Pen to a microcontroller or a computer, follow this structure:
VCC (Pin 1) -> 5V to 12V Power Supply or Battery +
GND (Pin 2) -> Power Supply or Battery - / Microcontroller GND
CLK (Pin 3) -> Microcontroller Digital Output (e.g., Pin 13 on Arduino Uno)
DIR (Pin 4) -> Microcontroller Digital Output (e.g., Pin 12 on Arduino Uno)
EN (Pin 5) -> Microcontroller Digital Output (e.g., Pin 11 on Arduino Uno)
T (Pin 6) -> Microcontroller Analog Input (e.g., A0 on Arduino Uno) or Dedicated Temperature Sensor Amplifier
Important Notes
Ensure proper voltage and current supply to the 3D Printing Pen to avoid damage.
Use a suitable motor driver or controller to drive the pen's motor, if not already integrated into the pen.
For temperature sensor input (Pin 6), a dedicated amplifier or analog-to-digital converter (ADC) might be required, depending on the specific pen model and microcontroller used.
Consult the microcontroller's documentation for pinouts and connection guidelines.
By following this documentation, you can successfully connect and control your 3D Printing Pen using a microcontroller or computer.

### Example 1: Basic Line Drawing using Arduino

In this example, we will use an Arduino board to control the 3D Printing Pen and draw a simple line.

Hardware Requirements

3D Printing Pen
 Arduino Board (e.g., Arduino Uno)
 USB cable

Software Requirements

Arduino IDE (version 1.8.x or later)

Code
```cpp
// Define the pen's serial communication pin
#define PEN_SERIAL_PIN 9

void setup() {
  // Initialize the serial communication
  Serial.begin(9600);
  pinMode(PEN_SERIAL_PIN, OUTPUT);
}

void loop() {
  // Set the pen's temperature to 200C
  Serial.print("M104 T:200
");
  delay(500);

// Move the pen to the starting position (x, y, z)
  Serial.print("G1 F100 X10 Y10 Z10
");
  delay(100);

// Draw a line from (10, 10, 10) to (50, 50, 10)
  Serial.print("G1 F100 X50 Y50 Z10
");
  delay(1000);

// Turn off the pen's motor
  Serial.print("M18
");
  delay(500);
}
```
### Example 2: Creating a Simple Shape using Python and BLE

In this example, we will use a Python script to control the 3D Printing Pen over Bluetooth Low Energy (BLE) and create a simple square shape.

Software Requirements

Python 3.x
 BlueZ library (for BLE communication)

Code
```python
import bluez

# Initialize the BLE connection
pen_ble_address = "12:34:56:78:90:AB"
pen_ble_service_uuid = "0000abcd-1234-5678-90ab-cdef01234567"
pen_ble_characteristic_uuid = "0000abcd-1234-5678-90ab-cdef01234568"

pen_ble = bluez.BlueZ()
pen_ble.connect(pen_ble_address)

# Set the pen's temperature to 200C
pen_ble.write_characteristic(pen_ble_service_uuid, pen_ble_characteristic_uuid, b"M104 T:200
")

# Move the pen to the starting position (x, y, z)
pen_ble.write_characteristic(pen_ble_service_uuid, pen_ble_characteristic_uuid, b"G1 F100 X10 Y10 Z10
")

# Draw a square shape
pen_ble.write_characteristic(pen_ble_service_uuid, pen_ble_characteristic_uuid, b"G1 F100 X20 Y10 Z10
")
pen_ble.write_characteristic(pen_ble_service_uuid, pen_ble_characteristic_uuid, b"G1 F100 X20 Y20 Z10

pen_ble.write_characteristic(pen_ble_service_uuid, pen_ble_characteristic_uuid, b"G1 F100 X10 Y20 Z10
")
pen_ble.write_characteristic(pen_ble_service_uuid, pen_ble_characteristic_uuid, b"G1 F100 X10 Y10 Z10
")

# Turn off the pen's motor
pen_ble.write_characteristic(pen_ble_service_uuid, pen_ble_characteristic_uuid, b"M18

# Disconnect from the pen
pen_ble.disconnect()
```
