To Whomever,

   I am trying to make a board that can control a 5 groups of lights that would all come on at different times.  This circuit has a light with 12-24v lights. 

group 1 say comes on in 30seconds

group 2 comes on in 80s

group 3 comes on in 130s

group 4 comes on in 180s

group 5 comes on in 230s

The purpose of this circuit is to make a group of street lights come on at different times in a line up.  I have a average mind on electronics and have put some boards together that are simple.  So I need a little help so i can make my idea work.  I have tried to put it together before but ran into some problems.  Any how i was thinking a switch would turn the the boards on which in turn lead to the lights.  Now on the board i thought that 5 555timers would work to get the lights to come on at differnt times.  A adjustable resistor would allow for how long it takes for the light to go on and a capacitor would allow for how long the light would stay on(about 8 hours).  I was thinking of putting the board on the ground side of the wire so the board dont have 12-24v flowing through it to burn the board up, but not sure if that would work.  Well if anyone has any ideas or knows of someone who could help with the idea that would be fantastic.  I was also thinking of using a relay but would like if i could leave it out cause they are expensive lol.   well anyhow post your ideas or thoughts that would be great.  If anything i said dont make sense write me and i see if i can clearify what i said. gla
