This is a revision of a previously posted project.
Now I require a completed working unit that will sequence the illumination of three banks of LED's.
The three banks will be of different colours RED, WHITE, GREEN. Each bank should be switched on in turn, however I do not want the LEDs just to switch on and off they should be increased in intensity from Off to Full On to Full Off again.
Red Increases to Full
Red Decreases to Off
White Increases to Full
White Descrease to Off
Green Increases to Full
Green Descreaes to Off
Return to Start again.
Full cycle time should be around 90 secs
The LED's are in banks that require 12v DC, to dim them the circuit is required to pulse between 12v and 0v to give the effect of dimming by altering the mark/space ration.
Max Current per LED bank approx 500ma.
