Gregad Posted February 8, 2012 Report Share Posted February 8, 2012 I am looking for circuit designs for a multi SMD 12 volt scanning circuit. All I can find uses 9 leds.I want to use high bright SMD or other leds and have them scan at least 30 to 60 leds from one end to the other. It must have supply voltage of 12 volts DC.I haven't considered leds values yet except for brightness until I can find a circuit to do this with and will order leds then.

Hero999 Posted February 8, 2012 Report Share Posted February 8, 2012 What's an LED scanner? Don't you mean a sequencer of chaser?Two CD4017s and some transistors could be used to do this. Quote Link to comment Share on other sites More sharing options...
