Good Day Sir/Ma'am,
I'm a technician and I am in need of schematic diagram of a sequential four transistor driven relay which i will needing for my project as part of my study. I have a single input source driven by LDR, the first relay should be turne d on and then off,while the second, third and fourth relay should be remain off, then when the LDR is active the second relay should be turned on and then off for a few seconds. and so with the third and fourth relay. when on e relay is active the other should not be active.
thank you very much.
