There is something I don't understand. Many tutorials say that by regulating an LDR or potentiometer you can regulate the analog value. Arduino guide says it is done by converting voltage to this value between 0 and 1023. The thing I don't understand is the fact that resistors don't regulate voltage…

Converting voltage to analog value with resistor

So is the other resistor in the arduino? Because you can get an analog value just with one pot/LDR.
