But i'm having a slight problem. If R1 is 250k ohms, R2 is 2k ohms and the Cap is 470 uf the LED will stay on for a minute and a half and then go off for 1/3 of a second.
I want it to go the other way, have it off for a minute and a half and then blink for 1/3 of a second but if you just switch R1 and R2 you get an equal time on and off, or atleast thats want it's supost to be acording to my time calculator.
Can anyone give me some help with this, its eather devilishly simple or really freaking hard...
