I was trying to get the values of a LDR and I noticed that the analog pin in the arduino has a default value in it. int analogInPin = A0; int sensorValue = 0; void setup() { Serial.begin(9600); } void loop() { sensorValue = analogRead(analogInPin); Serial.print("\t \n sensor = " ); Serial.p…

Analog pin has a constant value
