Examples
int inpin = 0;
int val = 0;
void setup() {
Serial.begin(9600);
}
void loop() {
val = analogRead(inpin); // read the value of analog pin 0
Serial.print(val / 4); // write the scaled value to the serial port
}
Description
The analogRead() method reads the value of an analog input pin. Possible values range from 0 to 1024, where 0 is 0 volts and 1024 is 5 volts.
