17. Interfacing

18. Code Logic ADC reads value Convert it to digital value
Send the Voltage value to LCD as output

19. Ammeter ADC reads value Convert it to digital value
Send the Current value to LCD as output

20. Power Factor Meter Using OP-AMP as comparator
When current wave form hits 0 value a timer starts
When voltage wave form hits 0 it stops timer
Time difference is calculated
Through formula as shown before angle is calculated
