Code Examples

### Example 1: Powering an Arduino Project

In this example, we will use the 12V 2A SMPS to power an Arduino Uno board and a few peripherals.

```c
// No code is required for this example, as the 12V 2A SMPS provides a stable power source
// for the Arduino board and peripherals.

// Connect the 12V 2A SMPS output to the Arduino Uno's Vin pin and GND pin.
// Connect your peripherals (e.g., sensors, LEDs, motors) to the Arduino Uno's digital and analog pins.
```

### Example 2: Powering a Raspberry Pi with Sensors and Actuators

In this example, we will use the 12V 2A SMPS to power a Raspberry Pi, a temperature sensor, and a relay module.

```python
# Import required libraries
import RPi.GPIO as GPIO
import time

# Set up GPIO pins for the relay module
GPIO.setmode(GPIO.BCM)
GPIO.setup(17, GPIO.OUT)  # Relay module control pin

try:
    while True:
        # Read temperature sensor data (not shown)
        # Control the relay module based on temperature readings
        GPIO.output(17, GPIO.HIGH)  # Turn on relay module
        time.sleep(1)
        GPIO.output(17, GPIO.LOW)  # Turn off relay module
        time.sleep(1)

except KeyboardInterrupt:
    GPIO.cleanup()
```

Note: In both examples, ensure that the 12V 2A SMPS is properly connected to the AC power source and the output is connected to the device being powered (Arduino Uno or Raspberry Pi). Additionally, follow proper safety precautions when working with electrical components.
