    HELP - resistors and dip-switch

    Hi, Virus The circuit you attached could possibly have some drawing defects, but the first thing I noticed was that pin 8 of the 555 is not connected to anything.

    need a simple project

    Here's a project that meets all your requirements, and is showy, also. The circuit demonstrates how an operational amplifier is able to accurately follow the flucuations of an input voltage, either positive or negative.

    HELP - resistors and dip-switch

    Hi Virus, If you were going to lift a circuit from that site, why didn't pick the one that WILL WORK! The attatched is from the same source, but unaltered, and is what we've been trying to accomplish lo these many days. Try it.
