Hi,
I posted on here a long time ago with my idea for a circuit I wanted to build, someone kindly pointed me to a couple of diagrams which I tried to build on breadboard but could not get to work, then I got side tracked and the idea was shelved for a while. I got all the parts from Maplin which was cheap except the breadboard.
I have now returned to trying to build this and would like some help if possible.
I am a complete novice as I have not done electronics since school so please treat me as a child.
My project is as follows:-
I want to have a bank of 12v 1.1w led bulbs powered from a car battery which is switched on at dusk, but the duration of the lights being adjustable due to seasonal requirements, Eg longer in the winter etc.
My thoughts were a dusk sensor, which when energised (eg goes dark) would power a timed on circuit which in turn would energise a relay. The timer would be adjustable via a pot. Hope that is the right word.
The circuits could also be powered via the 12v car battery.
Hope that makes sence.
I want to get this on a bread board and get it working before I take it across to strip board etc.
Any help would be great
