Hi all,
I am a complete newby and have not done anyform of electronics since at school, and that was many years ago.
I am trying to design a circuit and it may have already been done before, it is on the basis of a solar garden light but I want to time its duration it is on, for example 2hours after the dusk sensor has triggered it.
I am intending to use a 12v car battery and some 4w led lights.
I would presume I need a relay to operate the on off switch for the lights and the supply to this unit would be done using a timed supply that would run off the 12v car battery once activated by the dusk sensor.
Am I on the right tracks? Has this been done before and someone can point me in the direction of a previously completed design/project.
Cheers
Dickspanner
