Code Examples

### Example 1: Power Supply Filtering Circuit (Arduino)

In this example, we will use the 4700uF 25V Electrolytic Capacitor to filter the output voltage of a power supply to reduce ripple and noise.

```c++
// Define the capacitor pin connections
const int VIN_PIN = A0;  // Input voltage pin
const int VOUT_PIN = A1; // Output voltage pin
const int GND_PIN = GND; // Ground pin
const int CAP_PIN = 2;  // Capacitor pin

void setup() {
  pinMode(VIN_PIN, INPUT);
  pinMode(VOUT_PIN, OUTPUT);
  pinMode(GND_PIN, OUTPUT);
  pinMode(CAP_PIN, OUTPUT);
}

void loop() {
  // Read the input voltage
  int vin = analogRead(VIN_PIN);

// Apply the voltage to the capacitor
  analogWrite(VOUT_PIN, vin);

// Filter the output voltage using the capacitor
  analogRead(CAP_PIN);

// Read the filtered output voltage
  int vout = analogRead(VOUT_PIN);

// Print the filtered output voltage
  Serial.print("Filtered Output Voltage: ");
  Serial.print(vout);
  Serial.println(" mV");
}
```

### Example 2: Audio Filter Circuit (Raspberry Pi)

In this example, we will use the 4700uF 25V Electrolytic Capacitor to create a simple low-pass filter for an audio signal using a Raspberry Pi.

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

# Define the capacitor pin connections
VIN_PIN = 17  # Input audio signal pin
VOUT_PIN = 23  # Output audio signal pin
GND_PIN = 25  # Ground pin
CAP_PIN = 24  # Capacitor pin

# Set up the GPIO pins
GPIO.setmode(GPIO.BCM)
GPIO.setup(VIN_PIN, GPIO.IN)
GPIO.setup(VOUT_PIN, GPIO.OUT)
GPIO.setup(GND_PIN, GPIO.OUT)
GPIO.setup(CAP_PIN, GPIO.OUT)

# Define the filter constants
C = 4700e-6  # Capacitance (Farads)
R = 1000  # Resistance (Ohms)

# Define the filter cutoff frequency (Hz)
fc = 1 / (2  math.pi  math.sqrt(R  C))

while True:
    # Read the input audio signal
    vin = GPIO.input(VIN_PIN)

# Apply the audio signal to the capacitor
    GPIO.output(VOUT_PIN, vin)

# Filter the audio signal using the capacitor
    time.sleep(1 / fc)

# Read the filtered audio signal
    vout = GPIO.input(VOUT_PIN)

# Print the filtered audio signal
    print("Filtered Audio Signal:", vout)
```

Note: These code examples are simplified and may require additional components and configuration to function properly. They are intended to demonstrate the basic usage of the 4700uF 25V Electrolytic Capacitor in different contexts.
