Pin Configuration

Component Documentation: 8025 12V DC Cooling Fan
Pinout Explanation:
The 8025 12V DC Cooling Fan has a standard 3-pin power connector, allowing for easy integration into various IoT projects and applications. Below is a detailed explanation of each pin:
Pin 1: Positive (Red Wire)
Function: +12V DC Power Input
Description: This pin supplies the positive voltage to the fan motor, enabling its operation.
Connection: Connect to a 12V DC power source (e.g., a power supply, battery, or DC-DC converter).
Pin 2: Negative (Black Wire)
Function: 0V (Ground) Connection
Description: This pin provides a return path for the current drawn by the fan motor, completing the circuit.
Connection: Connect to the negative terminal of the power source (e.g., power supply, battery, or DC-DC converter) or a common ground point in the system.
Pin 3: Tachometer (Yellow Wire)
Function: Fan Speed Signal Output
Description: This pin provides a pulse signal indicating the fan's rotational speed. The frequency of the signal is proportional to the fan's RPM.
Connection: Connect to a microcontroller, sensor, or monitoring device to measure and track the fan's speed.
Connection Structure:
To connect the 8025 12V DC Cooling Fan, follow this step-by-step guide:
1. Power Connection:
Connect the Red Wire (Pin 1) to the positive terminal of a 12V DC power source.
Connect the Black Wire (Pin 2) to the negative terminal of the power source or a common ground point in the system.
2. Tachometer Connection (Optional):
Connect the Yellow Wire (Pin 3) to a microcontroller, sensor, or monitoring device to measure the fan's speed.
Ensure the connected device can handle the pulse signal and interpret the fan speed correctly.
Important Notes:
Ensure a secure and reliable connection to avoid loose connections, which can lead to fan malfunction or failure.
Verify the power source's output voltage and current ratings to ensure they match the fan's specifications.
Avoid overloading the fan with excessive voltage or current, as this can cause damage or reduce its lifespan.
By following this documentation, you should be able to properly connect and utilize the 8025 12V DC Cooling Fan in your IoT projects and applications.

Code Examples

### Example 1: Basic Fan Control using Arduino

In this example, we will control the fan ON/OFF using an Arduino board.

```c++
const int fanPin = 9;  // Fan connected to digital pin 9

void setup() {
  pinMode(fanPin, OUTPUT);
}

void loop() {
  digitalWrite(fanPin, HIGH);  // Turn the fan ON
  delay(5000);               // Wait for 5 seconds
  digitalWrite(fanPin, LOW);  // Turn the fan OFF
  delay(5000);               // Wait for 5 seconds
}
```

### Example 2: Fan Speed Control using Raspberry Pi (Python)

In this example, we will control the fan speed using a Raspberry Pi and Python.

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

GPIO.setmode(GPIO.BCM)
fan_pin = 18  # Fan connected to GPIO 18
GPIO.setup(fan_pin, GPIO.OUT)

try:
    while True:
        # Set fan speed to 50% (6V)
        GPIO.PWM(fan_pin, 50).start(50)
        time.sleep(5)
        # Set fan speed to 100% (12V)
        GPIO.PWM(fan_pin, 100).start(100)
        time.sleep(5)
except KeyboardInterrupt:
    GPIO.cleanup()
```

### Example 3: Fan Control using ESP32 (MicroPython)

In this example, we will control the fan ON/OFF using an ESP32 board and MicroPython.

```python
import machine
import time

fan_pin = machine.Pin(32, machine.Pin.OUT)

while True:
    fan_pin.value(1)  # Turn the fan ON
    time.sleep(5)
    fan_pin.value(0)  # Turn the fan OFF
    time.sleep(5)
```

Note: In the above examples, make sure to replace the pin numbers with the actual pins used on your board. Also, ensure that the power supply can provide enough current to the fan.

Troubleshooting

If the fan does not spin, check the power supply and connections.
 If the fan is noisy, check for loose screws or misaligned blades.
 If the fan does not respond to speed control signals, check the PWM frequency and duty cycle.
