Hie guys i am working on a project to progress the above circuit by encooperating a 7 segment led display . Basically i have made the dark sensor turn on a relay once darkness falls. Once active, the relay pinout would supply 12v to an analogue delay circuit which will discharge after 5 seconds thereby turning on an LED. Literally i have built a 555 timer circuit which will also be triggered by the relay vout at 12v. Now i need the pulses from the 555 delay circuit to feed into the IC of any proposed digital display circuit operating at between 5v and 12. The above circuit operates at 12v and if any of your proposed digital displays works under a lower threshold, i would be pleased to feed the circuit through a calculated POTENTIAL DEVIDER to reduce voltage.
In essence, i am pleading for schematics and pin layout for a BCD,7 segment display circuit.
Cheers !
