Pinout Description
The 40W Hot Melt Glue Gun has a total of 4 pins, which are used to control and power the device. Below is a detailed description of each pin and its function.
Pin 1: VCC (Power Supply)
Function: Provides power to the glue gun's heating element and internal circuitry.
Voltage: 12V DC (Recommended operating voltage)
Current: Up to 3.33A (Maximum current rating)
Connection: Connect to a 12V DC power source, such as a wall adapter or battery.
Pin 2: GND (Ground)
Function: Provides a common ground connection for the glue gun's internal circuitry.
Connection: Connect to the negative terminal of the power source or a common ground point in the system.
Pin 3: TRIG (Trigger)
Function: Activates the glue gun's heating element when pulled low (connected to GND).
Logic: Active low, internal pull-up resistor.
Connection: Connect to a digital output pin on a microcontroller or a switch that can pull the pin low to activate the glue gun.
Pin 4: LEDs (Indicator)
Function: Indicates the operating status of the glue gun:
+ Red LED: Heating element is active (glue gun is hot)
+ Green LED: Heating element is inactive (glue gun is cold)
Connection: Connect to a voltage source (5V or 12V) through a current-limiting resistor (e.g., 1k) to prevent overheating.
Connection Structure
To connect the 40W Hot Melt Glue Gun, follow this structure:
1. Power Connection:
Connect Pin 1 (VCC) to the positive terminal of a 12V DC power source (e.g., wall adapter or battery).
Connect Pin 2 (GND) to the negative terminal of the power source or a common ground point in the system.
2. Trigger Connection:
Connect Pin 3 (TRIG) to a digital output pin on a microcontroller or a switch that can pull the pin low to activate the glue gun.
3. Indicator Connection:
Connect Pin 4 (LEDs) to a voltage source (5V or 12V) through a current-limiting resistor (e.g., 1k) to prevent overheating.
Important Notes
Ensure the power supply can provide the recommended voltage and current ratings to avoid damage to the glue gun.
Use a suitable current-limiting resistor for the indicator LEDs to prevent overheating.
Avoid short-circuiting the pins or connecting them to incorrect voltage sources, as this may damage the glue gun.
By following these guidelines, you can successfully connect and operate the 40W Hot Melt Glue Gun in your IoT project.

### Example 1: Basic Temperature Control using Arduino

This example demonstrates how to control the temperature of the hot melt glue gun using an Arduino Board.

```c
#include <Wire.h>

#define GLUE_GUN_ADDRESS 0x1F // I2C address of the glue gun
#define TEMP_SETPOINT 200 // Desired temperature (C)

void setup() {
  Wire.begin(); // Initialize I2C communication
  Serial.begin(9600); // Initialize serial communication for debugging
}

void loop() {
  int currentTemp = readTemperature(GLUE_GUN_ADDRESS);
  Serial.print("Current Temperature: ");
  Serial.print(currentTemp);
  Serial.println("C");
  
  if (currentTemp < TEMP_SETPOINT) {
    setHeater(GLUE_GUN_ADDRESS, true); // Turn on the heater
  } else {
    setHeater(GLUE_GUN_ADDRESS, false); // Turn off the heater
  }
  delay(1000); // Wait for 1 second before taking the next reading
}

int readTemperature(int address) {
  Wire.beginTransmission(address);
  Wire.write(0x01); // Register address for temperature reading
  Wire.endTransmission();
  Wire.requestFrom(address, 2);
  int temp = Wire.read() << 8 | Wire.read();
  return temp;
}

void setHeater(int address, bool state) {
  Wire.beginTransmission(address);
  Wire.write(0x02); // Register address for heater control
  Wire.write(state ? 0x01 : 0x00); // Turn on/off the heater
  Wire.endTransmission();
}
```

### Example 2: Advanced Temperature Control and Monitoring using Python

This example demonstrates how to control and monitor the temperature of the hot melt glue gun using a Raspberry Pi and Python.

```python
import serial
import time

# Open the serial connection to the glue gun
ser = serial.Serial('/dev/ttyUSB0', 9600, timeout=1)

def read_temperature():
  ser.write(b't') # Request temperature reading
  response = ser.readline().decode().strip()
  return int(response)

def set_temperature(temp_setpoint):
  ser.write(f's{temp_setpoint}'.encode()) # Set temperature setpoint
  response = ser.readline().decode().strip()
  return response == 'ok'

def monitor_temperature():
  while True:
    temp = read_temperature()
    print(f'Current Temperature: {temp}C')
    if temp < 200:
      print('Heater ON')
    else:
      print('Heater OFF')
    time.sleep(1)

# Set temperature setpoint to 220C
set_temperature(220)

# Monitor temperature
monitor_temperature()
```
