Analog Sensor

I used conductive tape and paint in order to create an analog sensor. One of the two LEDs is lighted by the circuit, according to the voltage of the potentiometer.

int inputPin = A0;
int WhiteLED = 13;
int RedLED = 3;

void setup() {
pinMode(inputPin, INPUT);
pinMode(WhiteLED, OUTPUT);
pinMode(RedLED, OUTPUT);

void loop() {
// put your main code here, to run repeatedly:
int value = analogRead(inputPin);
int ledValue = map(value, 0, 1023, 0, 255);

if (ledValue >= 100) {
analogWrite(WhiteLED, ledValue);
digitalWrite(RedLED, LOW);
delay (1000);

else {
analogWrite(RedLED, ledValue);
digitalWrite(WhiteLED, LOW);
delay (1000);
