Dear sir
I made Remote control of home appliance circuit . circuit is attached. I am facing problem that relay is tripping after few minutes automatically. I have covered TSOP1738 by small paper so that it should not be disturbed by nearby IR rays. I connected 220V, 40W bulb with Common point and NC terminal of relay. My relay is 6V dc has coil resistance of 103 Ohm. i am using 7805 regulator for 5V dc supply for this circuit. My bulb is tripping ON and OFF automatically after every few minutes. I am unable to understand why this happening?
Please help me to fix this problem as you are known to best in electronic circuit trouble shootings.
Thanks
