[snufkin]

hey guys

im doing a project where i need a circuit that when a switch is depressed holds it on for a short amount of time even some kind of relay circuit 

do any of you know of one somewhere on the net ? mabe a 555 circuit or somthing or even one in kit form (i looked and could only find on/of timers)

thanks dont put yourselves to any trouble though

this will do the timing part of things

(refer the the section a page up for what to do with pins #4 and #5)


then take the output to control whatever you're want to do with it (eg: a transistor thats switching a relay)
