For more advanced projects, you might need a sensor that provides high accuracy and communicates via a digital protocol.
// Calculate input voltage using divider formula vin = vout / (R2 / (R1 + R2));
Open your Proteus Schematic Capture window and press on your keyboard to open the "Pick Devices" window. Search for and select the following: Arduino UNO (Requires Arduino Proteus Library) Voltage Sensor (The library you just installed) voltage sensor proteus library
: Close and reopen the software so it can index the new components. Pick Device (P)
For AC voltage sensing (e.g., 230V mains), the module is popular. Some Proteus enthusiasts have modeled it. Look for "ZMPT101B Proteus library" on GitHub or Electro-Tech-Online forums . For more advanced projects, you might need a

If the simulation runs slow, it’s often due to "Real-time simulation failed." Try simplifying your AC source frequency if you are only testing logic. Pick Device (P) For AC voltage sensing (e
: Check the step-down ratio in the component properties. Right-click the sensor, select Edit Properties , and modify the internal scaling factors if provided by the library developer.
Use the "Pick Devices" (P) tool and search for "Voltage Sensor" or the specific part name (e.g., MC34064 for low voltage detection) to add it to your schematic. Simulation Tips
