Pinout Explanation
The 5V 0.2A 3010 Raspberry Pi Cooling Fan has a total of 3 pins, which are used to power and control the fan. Below is a detailed explanation of each pin:
### Pin 1: VCC (Positive Power Supply)
Description: This pin supplies the positive voltage to the fan.
Voltage: 5V
Current: Up to 0.2A
Connection: Connect this pin to the 5V power output of your Raspberry Pi or a suitable 5V power source.
### Pin 2: GND (Ground)
Description: This pin provides the ground connection for the fan.
Voltage: 0V
Connection: Connect this pin to the GND (Ground) pin of your Raspberry Pi or a suitable ground connection.
### Pin 3: None (No Connection)
Description: There is no connection or functionality associated with this pin. Leave it unconnected.
Connecting the Pins
To connect the fan to your Raspberry Pi, follow these steps:
1. Identify the fan pins: Locate the three pins on the fan, labeled as VCC, GND, and the unused pin.
2. Identify the Raspberry Pi pins: Identify the corresponding pins on your Raspberry Pi, typically labeled as 5V, GND, and others.
3. Connect VCC to 5V: Connect the VCC pin of the fan to a 5V power output pin on the Raspberry Pi. Typically, this is pin 2 or 4 on the Raspberry Pi header.
4. Connect GND to GND: Connect the GND pin of the fan to a GND pin on the Raspberry Pi. Typically, this is pin 6 or 9 on the Raspberry Pi header.
5. Leave the unused pin unconnected: Do not connect the unused pin on the fan to any pin on the Raspberry Pi.
Example Connection:
Here's an example connection diagram:
```
Fan Pin 1 (VCC) -> Raspberry Pi Pin 2 (5V)
Fan Pin 2 (GND) -> Raspberry Pi Pin 6 (GND)
Fan Pin 3 (Unused) -> No Connection
```
Important Notes:
Make sure to connect the fan correctly to avoid damage to the fan or your Raspberry Pi.
The fan's power consumption is rated at 0.2A, so ensure your power source can provide the required current.
If you're using a power supply other than the Raspberry Pi, ensure it can provide a stable 5V output and sufficient current.

Connecting the Fan to a Raspberry Pi

To connect the fan to a Raspberry Pi, you'll need to connect the fan's pins to the Raspberry Pi's GPIO header. The typical connection is:

VCC (red wire) to GPIO pin 2 (5V)
 GND (black wire) to GPIO pin 6 (GND)
 Signal (yellow wire) to GPIO pin 14 (GPIO 14)

Example 1: Controlling the Fan using GPIO

In this example, we'll use Python to control the fan's speed using the RPi.GPIO library.

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

# Set up GPIO mode
GPIO.setmode(GPIO.BCM)

# Set up fan pin as an output
GPIO.setup(14, GPIO.OUT)

try:
    while True:
        # Set fan speed to 50% ( PWM )
        GPIO.PWM(14, 50)
        time.sleep(1)
        # Set fan speed to 100% ( full speed )
        GPIO.PWM(14, 100)
        time.sleep(1)
except KeyboardInterrupt:
    GPIO.cleanup()
```
Example 2: Auto-Starting the Fan on Boot

In this example, we'll configure the fan to start automatically on boot using a systemd service.

Code:
```bash
# Create a new file in /etc/systemd/system called fan.service
sudo nano /etc/systemd/system/fan.service

# Add the following contents
[Unit]
Description=Raspberry Pi Fan Service
After=sysinit.target

[Service]
ExecStart=/usr/bin/python /home/pi/fan_control.py
Restart=always

[Install]
WantedBy=multi-user.target

# Save and exit

# Create a new file in /home/pi called fan_control.py
sudo nano /home/pi/fan_control.py

# Add the following contents
import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)
GPIO.setup(14, GPIO.OUT)
GPIO.output(14, GPIO.HIGH)

# Save and exit

# Reload systemd daemon and enable the service
sudo systemctl daemon-reload
sudo systemctl enable fan.service
sudo systemctl start fan.service
```
In this example, the `fan_control.py` script sets the fan to full speed (GPIO HIGH) on boot, and the `fan.service` file configures the script to run automatically on boot.

Example 3: Monitoring Temperature and Adjusting Fan Speed

In this example, we'll use Python to monitor the Raspberry Pi's temperature using the `vcgencmd` command and adjust the fan speed accordingly.

Code:
```python
import subprocess
import RPi.GPIO as GPIO

# Set up GPIO mode
GPIO.setmode(GPIO.BCM)

# Set up fan pin as an output
GPIO.setup(14, GPIO.OUT)

while True:
    # Get the current temperature
    temp = subprocess.check_output(["vcgencmd", "measure_temp"])
    temp = float(temp.decode("utf-8").replace("temp=", ""))

# Adjust fan speed based on temperature
    if temp > 50:
        GPIO.output(14, GPIO.HIGH)  # Full speed
    elif temp > 40:
        GPIO.output(14, GPIO.LOW)  # Half speed
    else:
        GPIO.output(14, GPIO.LOW)  # Off

time.sleep(1)
```
In this example, the script monitor's the Raspberry Pi's temperature and adjusts the fan speed accordingly. If the temperature exceeds 50C, the fan runs at full speed. If the temperature is between 40C and 50C, the fan runs at half speed. Otherwise, the fan is turned off.
