Hi there!

I connected 5V to analog pin 0 and run this code:

Code: [Select]
int sensorPin = 0;    // select the input pin for the potentiometer// select the pin for the LED
int sensorValue = 0;  // variable to store the value coming from the sensor

void setup() {

void loop() {
 sensorValue = analogRead(sensorPin);    

All i got is ÿ as output to serial monitor, what's up with that? Shouldn't it give 1023 as output?

Have to use serial.print instead of serial.write ::)
