Simulating AC mains voltage safely is a nightmare for most hobbyists. One wrong probe, and your $50 USB oscilloscope is toast. Enter the ZMPT101B —a popular, isolated AC voltage sensor module. But how do you test your Arduino or ESP8266 code without frying real hardware? lcd.print(" V AC")

#include <LiquidCrystal.h> LiquidCrystal lcd(12, 11, 5, 4, 3, 2); float voltageRMS = 0; float readValue = 0; float Vref = 2.5; // Output offset of ZMPT101B (adjust based on simulation)

The answer is and a reliable ZMPT101B library .
