    i open a weight scale and i saw 2 metal strips on each side with wires connected, battery, digital readout and 1 of the legs wired. i dont want to fix it, but i'd to use the readout, so i connected the bat. ramdomlytrying to lit each of the readout segments, but it gave me a big number. This readout has a black round that i know is a kind of transistor.
    How i make the readout segments lit one by one ??

    How do you come to know this? My guess is that it's a complex integrated ciruit who's package is a drop of epoxy opposed to rectangular box.
