In the real world, an Arduino or PIC microcontroller cannot directly read high voltages (e.g., 12V or 24V) because their GPIO pins are rated for 5V or 3.3V. In Proteus, you need a sensor model that mimics this behavior: voltage sensor proteus library

If you see "No Simulator Model," ensure you have correctly placed the .LIB files in the DATA\LIBRARY folder, not just the root folder. Most hobbyists use the or the "New Sensors

Most hobbyists use the or the "New Sensors Library for Proteus" created by third-party developers like The Engineering Projects. Steps to Install:

float vout = 0.0; float vin = 0.0; float R1 = 30000.0; float R2 = 7500.0; int value = analogRead(A0); vout = (value * 5.0) / 1024.0; vin = vout / (R2 / (R1 + R2)); Use code with caution.

Using 30k and 7.5k resistors, a 25V input becomes exactly 5V, making it perfectly safe for an Arduino analog pin. Step-by-Step Simulation Guide
