This Arduino project involves measuring both AC and DC voltages using the ZMPT101B voltage sensor and an analog pin, respectively. The AC voltage is read from the ZMPT101B sensor connected to pin A0, while the DC voltage is read from an analog pin (A1). The measured values are displayed on a 16x2 LCD screen with I2C communication and printed via Se
