When I power it up it works just fine. It responds to the light. But after it is working about 20 minutes when I shadowed the ldr it switched off the relay but when I removed the shadow it does not activate the relay anymore. Now when I switch off the whole thing for 30 minutes it again starts and then after 20 minutes if I cover the ldr same old story.
What is wrong with this circuit. How can I get a reliable service?
Thanks in advance.
