i was just looking up the diagram and the explaination of how the 555 works. It looks like the monostable mode works oppisite of what i would like to do. i would like to see 0 output voltage for 3 seconds after i hit a switch, then after about 3 seconds i would like to see full Vcc voltage at the out put. I might be wrong, but it seems i might be able to wire it up to do this, im just not sure how. as it is described in monostable mode it is basically oppisite, turning the voltage off after 3 seconds or any giving time instead of on. Maybe someone can clear that up for me if they got the time? thanks
and also one other question, im looking at the diagram on wikipedia, i see the resistors, the transistor and the compacitor, but im wondering what the large triangles are. I assumeing a one way check vave, diode? Im not positive, been almost a year since i really looked to understand out a circuit worked. Thanks.
