Hello experts guys ! i m working on the project "Automatic Power Factor Correction using Atmega16". I took current sample from resistor (schematic attached) and provided this sample at PAO of Atmega16 . Further more i took Voltage samples from Zero cross detector and provided this sample at PINC.4. Finally i tested my circuit at Bread board and it was working perfect. It was showing accuate power factor. but when i buiilt this circuit at PCB it does not taking sample of either voltage or current. please help me to troubleshoot. i m totalyy exhausted....
