Hello, I need to build a circuit for a friend...and I'm a little lost.
I need to generate a DC output of about 6 volts, and have it alternate once every 11 minutes. (Out1 = +5 Out2 = G ----11 Minutes----> Out1 = G Out2 = +5 ------repeat----->)
Trying to figure out how to achieve this...Maybe a +6v regulator and -6v regulator, have it switch between the two when a pulse from a timer is given? The actual switching is the only problem. And it needs to be automatic, I'm not going to throw a switch manually every 11 minutes
As for the timer...11 minutes, odd yes...I have a few 555/556 timers and am familiar with those...never used one for more than a few second delay though. How could I best achieve one pulse every 11 minutes, without the use of a PIC?
Suggestions would be appreciated
