I am using ESP32 , TFT display (240x240) and  external 16 bit ADC module (ADS1115) to measure voltage.I  I just want to show you my simple voltmeter sketch. I am comparing my project with a real multimeter and results are quite good. I haven done any calibration and no external components are used.

Parts used in project:
