Hi All,
Target-PIC Mcu based IR REMOTE CONTROL To operate relay based AC LOAD. Section wise component as follows:
1) TRANSMITTER: IR REMOTE NEC protocal,
2) RECEIVER: TSOP1738,
3) ZERO CROSS: Transistor, resistor, ceramic capacitor based.
4) MCU: PIC 16F628A
5) POSER SUPPLY: TRANSFORMER 230/12V
Problems facing:
All are working correctly, but At some particular time of the day not getting output at MCU o/p pin.
If remove Zero-X, either from RB0 pin(Interrupt) or from Power i/p to zero-X Circuit from Diode-Bridge(ie, P_DC) then the ckt is working at that particular time of the day.
Why this behaves like starange?
Request Input for that issue please.
Tnx
