require a circuit diagram for a device 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
Max Current per LED bank approx 500ma.
