I think that 1/2V divider thing would work out pretty well... i THINK then new signal is 1/2 of the first (it SHOULD be) but not certain... I'l keep that in mind tho. The load is very small... its all running to a computer, so all it needs is enough power to travel the distance of the wire...

I had a system that used a gnd and a signal... then new system wants a gnd and two signals... Signal1 is the same, signal2 (new) is 1/2 signal 1... I sort of (almost kinda) understand what your saying, but just cant see any reason not to make a chip to do this... I'm thinking now of using a PIC...

I'm the tricking the new processor using the old switches game... The voltage is 5V always (reference) and the amps... well, I dont know the amps right now, but its low... like .5 or 1... think car switches... thats a good example. The Z8 Encore looks a little much for this application... I...

Ok... that was a little (lot) over my head :) Here is what I'm thinking now... Voltage = Current * Resistance right ? (v=ir) So then my system doesnt really care what the resistance is... It cares what the voltage is after hitting the resistor. (This is a revelation for me) So all i need...

To clear this up, I'm getting input from switches where each switch sends a 5V signal at a different resistance to a processor that reads that resistance then performs an action... My problem is I'm changing processors to a similar design but with a 'failsafe' system that requires all the...

First off, I'm extremely new at this... but I aint no fool :) I need a chip/curcuit (maybe single chip??) to read in 3 different wires and for each wire output two others (ie: 3 in | 6 out), but they all need to be different resistances... so for example: Wire1 is sending a 5V signal at...

I need a chip/curcuit (maybe single chip??) to read in 3 different wires and for each wire output two others (ie: 3 in | 6 out), but they all need to be different resistances... so for example: Wire1 is sending a 5V signal at 4.5ohm... this goes into the chip, and then the chip sends out two...

First off, I'm extremely new at this... but I aint no fool. And sorry about posting in different forums, but couldnt figure out where the best place was to post. I need a chip/curcuit (maybe single chip??) to read in 3 different wires and for each wire output two others (ie: 3 in | 6 out), but...
