Using the 12 MHz Crystal Oscillator with an Arduino Board

In this example, we'll demonstrate how to use the 12 MHz Crystal Oscillator with an Arduino Uno board to generate a stable clock signal.

Hardware Requirements

Arduino Uno board
 12 MHz Crystal Oscillator (from this pack)
 2 x 18 pF ceramic capacitors
 Breadboard and jumper wires

Software Requirements

Arduino IDE (version 1.8 or later)

Code Example
```c++
void setup() {
  // No setup required
}

void loop() {
  // Use the crystal oscillator as the clock source
  CLKPR = (1 << CLKPCE);  // Enable clock prescaler change
  CLKPR = (1 << CLKPS0) | (1 << CLKPS1) | (1 << CLKPS2);  // Set clock prescaler to 1
  while (1) {
    // Your code here
  }
}
```
In this example, we're using the crystal oscillator as the clock source for the Arduino Uno board. We enable the clock prescaler change, and then set the clock prescaler to 1, which allows the board to use the 12 MHz clock signal from the crystal oscillator.

Using the 12 MHz Crystal Oscillator with a Raspberry Pi (RPi)

In this example, we'll demonstrate how to use the 12 MHz Crystal Oscillator as an external clock source for a Raspberry Pi (RPi) board.

Hardware Requirements

Raspberry Pi board (any model)
 12 MHz Crystal Oscillator (from this pack)
 2 x 18 pF ceramic capacitors
 Breadboard and jumper wires

Software Requirements

Raspbian OS (any version)

Code Example
```python
import time

# Set the external clock source
with open("/sys/devices/system/clocksource/clocksource0/current_clocksource", "w") as f:
    f.write("extclk")

# Verify the clock frequency
with open("/sys/devices/system/clocksource/clocksource0/current_clock", "r") as f:
    clock_frequency = int(f.read())
    print("Clock frequency:", clock_frequency)
```
In this example, we're using the 12 MHz Crystal Oscillator as an external clock source for the Raspberry Pi board. We set the external clock source using the `current_clocksource` file, and then verify the clock frequency by reading the `current_clock` file.

Important Notes

When using the 12 MHz Crystal Oscillator with a microcontroller or other digital circuit, ensure that the load capacitance is matched to the crystal's specified value (18 pF in this case).
 The crystal oscillator should be handled carefully to avoid damage or degradation due to mechanical stress, moisture, or excessive voltage.
 Consult the datasheet and application notes for specific instructions on using the 12 MHz Crystal Oscillator with your chosen microcontroller or system.
