WebTo start, we need to define the pin as an input. To match the circuit diagram we will use A3: pinMode(A3, INPUT); and then do the analog to digital version by using the analogRead () command: int x = analogRead(A3); //Reads the analog value on pin A3 into x The value that is returned and stored in x will be a value from 0 to 1023. Webintval converts doubles to integers by truncating the fractional component of the number. When dealing with some values, this can give odd results. Consider the following: print intval ( (0.1 + 0.7) * 10); This will most likely print out 7, instead of the expected value of 8.
