    IR gate counter HELP!

    Thankyou for your response, but being new into the ic world I have no idea how to wire such a thing... So maybe more of what I was asking is there anywhere I could find a schematic of such a thing?

    IC Help

    I don't know. I know very little about IC's and not enough to know the difference between them. I have used a 555 timer in one of my projects before, I got the directions ofline. It worked, but I don't know why or how it worked. This is a very vast topic I know... Is there a beggining to start at?

    led problem

    Again, thank you for your quick reply and of course the time you took to make the schematic for me. Alas, I have more questions... Is there anything that could be done to increase the life of the pot? ...and being a junior in high school and planning on at least minoring in electrical...
