Code Examples

### Example 1: Basic Voltage Regulation using Arduino

This example demonstrates how to use the 220V 4000W SCR Voltage Regulator module with an Arduino board to regulate the output voltage.

```c++
const int adjPin = A0; // ADJ pin connected to Arduino Analog Input 0
const int outputVoltage = 150; // Desired output voltage (150V AC)

void setup() {
  pinMode(adjPin, OUTPUT);
  analogWrite(adjPin, map(outputVoltage, 0, 220, 0, 255)); // Set output voltage using PWM
}

void loop() {
  // No code required in the loop, as the output voltage is set in the setup function
}
```

In this example, the ADJ pin is connected to an Arduino analog output. The `analogWrite()` function is used to set the output voltage by generating a PWM signal. The `map()` function is used to scale the desired output voltage (150V AC) to a corresponding PWM value.

### Example 2: Motor Speed Control using Raspberry Pi

This example demonstrates how to use the 220V 4000W SCR Voltage Regulator module with a Raspberry Pi to control the speed of a motor.

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

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

# Define ADJ pin as output
adj_pin = 17
GPIO.setup(adj_pin, GPIO.OUT)

try:
    while True:
        # Set output voltage to 100V AC (50% PWM duty cycle)
        GPIO.PWM(adj_pin, 50).start(50)
        time.sleep(1)

# Set output voltage to 150V AC (75% PWM duty cycle)
        GPIO.PWM(adj_pin, 50).start(75)
        time.sleep(1)

except KeyboardInterrupt:
    GPIO.cleanup()
```

In this example, the ADJ pin is connected to a Raspberry Pi GPIO output. The `RPi.GPIO` library is used to set up the GPIO mode and define the ADJ pin as an output. The `GPIO.PWM()` function is used to generate a PWM signal to control the output voltage. The motor speed is changed by adjusting the PWM duty cycle.

Safety Precautions

Handle the module with care, as it operates at high voltages and can cause electrical shock or injury.
 Ensure proper heat dissipation to prevent overheating and damage to the module.
 Follow proper safety guidelines when working with high-voltage AC power.
