If you need help for a specific library version, or if you encounter errors during compilation , please let me know! Share public link

: Get the .LIB and .IDX (library) and .MOD (model) files from a reputable source like The Engineering Projects . Copy the files :

float readACVoltage(int pin) const int samples = 500; float sumSq = 0; for (int i = 0; i < samples; i++) int adc = analogRead(pin); // 0-1023 float voltage = (adc / 1023.0) * 5.0; // 0-5V float offsetRemoved = voltage - 2.5; // -2.5 to +2.5 sumSq += offsetRemoved * offsetRemoved; delayMicroseconds(400); // ~1kHz sampling

To power the internal simulated operational amplifier (usually 5V).

Some libraries are backward-compatible, but Proteus 7 has limited SPICE features. Search for legacy-specific ZMPT101B models.

Fully compatible with AVR (Arduino Uno/Mega) and ESP32/ESP8266.

If you need help setting up the in the Arduino code, or if you run into any compilation issues with your sketch inside Proteus, just let me know! Share public link

Route the OUT pin of the ZMPT101B directly to the A0 analog input pin of the Arduino Uno.
