Hi,

I am an engineering student and working on a circuit using 555 timer a stable mode that will help me for blinking LEDS project. I want to make LEDS off timing more longer than on timing… means if the LEDS on timer is 10 sec then it’s on timer must be 60 sec, is it possible to build such a circuit? Please help me out in this issue, what will be the equations of resistors and capacitors for this working such circuit?

Thanks.

Stewartjones, what Digi product are you working with to turn on and off these LED’s with?
