const int vin = 9; // Input voltage (9V)
const int vout = 5; // Desired output voltage (5V)void setup() {
// Initialize output pin as an output
pinMode(vout, OUTPUT);
}void loop() {
// Regulate input voltage to 5V
analogWrite(vout, vin (5.0 / 9.0));
delay(100);
}
```Example 2: Adjustable Output Voltage RegulatorIn this example, we will use the LM1117 to regulate a 12V input voltage to an adjustable output voltage between 1.8V and 5V.Schematic```

const int vout_min = 180; // Minimum output voltage (1.8V)
const int vout_max = 500; // Maximum output voltage (5V)void setup() {
// Initialize output pin as an output
pinMode(vout, OUTPUT);
}void loop() {
int vout_value = map(analogRead(A0), 0, 1023, vout_min, vout_max);
analogWrite(vout, vin (vout_value / 12.0));
delay(100);
}
```
In this example, the output voltage is adjusted using an external potentiometer connected to an analog input (A0) on the Arduino board. The `map()` function is used to scale the analog input value to the desired output voltage range.Note: These examples are meant to demonstrate the basic usage of the LM1117 IC and may require additional components and circuitry for a complete and functional project.
