Code Examples

Example 1: Basic Cooling System with Arduino

In this example, we'll demonstrate a basic cooling system using an Arduino board to control the fan and monitor the temperature.

```cpp
#include <Arduino.h>

// Thermistor pin connections
const int thermistorPin = A0;

// Fan pin connections
const int fanPin = 9;

void setup() {
  Serial.begin(9600);
  pinMode(fanPin, OUTPUT);
}

void loop() {
  // Read thermistor voltage
  int thermistorValue = analogRead(thermistorPin);
  
  // Calculate temperature in Celsius
  float temperature = thermistorValue  0.48828;
  
  // Display temperature
  Serial.print("Temperature: ");
  Serial.print(temperature);
  Serial.println(" C");
  
  // Control fan based on temperature
  if (temperature > 30) {
    digitalWrite(fanPin, HIGH);
  } else {
    digitalWrite(fanPin, LOW);
  }
  
  delay(1000);
}
```

Example 2: Raspberry Pi-based Temperature Control

In this example, we'll demonstrate a temperature control system using a Raspberry Pi and Python.

```python
import RPi.GPIO as GPIO
import time

# Thermistor pin connections
thermistorPin = 18

# Fan pin connections
fanPin = 23

# Set up GPIO pins
GPIO.setmode(GPIO.BCM)
GPIO.setup(fanPin, GPIO.OUT)

try:
    while True:
        # Read thermistor voltage
        thermistorValue = GPIO.input(thermistorPin)
        
        # Calculate temperature in Celsius
        temperature = thermistorValue  0.48828
        
        # Display temperature
        print("Temperature: {:.2f} C".format(temperature))
        
        # Control fan based on temperature
        if temperature > 30:
            GPIO.output(fanPin, GPIO.HIGH)
        else:
            GPIO.output(fanPin, GPIO.LOW)
        
        time.sleep(1)

except KeyboardInterrupt:
    GPIO.cleanup()
```

Example 3: Automatic Cooling System with ESP32

In this example, we'll demonstrate an automatic cooling system using an ESP32 board and MicroPython.

```python
import machine
import time

# Thermistor pin connections
thermistorPin = machine.Pin(32, machine.Pin.IN)

# Fan pin connections
fanPin = machine.Pin(25, machine.Pin.OUT)

while True:
    # Read thermistor voltage
    thermistorValue = thermistorPin.value()
    
    # Calculate temperature in Celsius
    temperature = thermistorValue  0.48828
    
    # Display temperature
    print("Temperature: {:.2f} C".format(temperature))
    
    # Control fan based on temperature
    if temperature > 30:
        fanPin.value(1)
    else:
        fanPin.value(0)
    
    time.sleep(1)
```

Troubleshooting and Safety Precautions

Ensure proper connection of the Peltier element, thermistor, and fan to the kit components.
 Use a suitable power source (12V, 5A) to avoid overheating or damage to the components.
 Monitor temperature and adjust the cooling system accordingly to avoid overheating or undercooling.
 Keep the cooling system away from flammable materials and ensure good airflow.
