const int voutPin = A1; // Output voltage pin
const int cermetPin = A2; // Cermet wiper pin
void setup() {
pinMode(vinPin, INPUT);
pinMode(voutPin, OUTPUT);
pinMode(cermetPin, INPUT);
}
void loop() {
int vinValue = analogRead(vinPin);
int cermetValue = analogRead(cermetPin);
int voutValue = map(cermetValue, 0, 1023, 0, vinValue);
analogWrite(voutPin, voutValue);
delay(10);
}
```

# Set up GPIO pins
GPIO.setmode(GPIO.BCM)
GPIO.setup(18, GPIO.OUT) # Audio output pin
GPIO.setup(23, GPIO.IN) # Cermet wiper pin
try:
while True:
cermet_value = GPIO.input(23)
audio_volume = cermet_value 255 / 1023
GPIO.output(18, audio_volume)
time.sleep(0.01)
except KeyboardInterrupt:
GPIO.cleanup()
```
These examples demonstrate how to use the 500K Cermet in different IoT applications. The cermet potentiometer can be used in a variety of other projects, such as sensor calibration, impedance matching, and signal attenuation.
