: Most standard DC voltage sensor libraries simulate the 0–25V range, typically using a voltage divider principle to step down higher voltages to a safe 0–5V signal for Arduino.
Serial.print("Input Voltage: "); Serial.println(vin); delay(500); voltage sensor proteus library
Check the "Reference Voltage" in your code. Proteus defaults to 5V; if your MCU is set to 3.3V, your math will be off. : Most standard DC voltage sensor libraries simulate
