I need help with switching signals

Former Member

Hi there

Although I know a thing or two (ok, maybe 1.5 things) about soldering, I am fairly new to this electronics thing. I've been thinking about starting a secret project that I will only share once I finish. I had trouble finding the materials I need such as the battery, the charging mechanism, ...etc. That is not important right now. As I was listing down the things I wanted it to do, I encountered something I don't know how to solve, thus I need your guys' help

Say I'm connecting two points together (let's call them A and B). Now, I need to switch the output from B to another point called D that gets it's signal from point C by pressing a button. Basically I want to flip the signals (you can think of it as cross multiply in math terms) Now you could say "just use a slide switch, you dummy" but the problem is I have 60 inputs and outputs. do you think you can help me with this?

I thought of using an EEPROM because they have a lot of pins so that I would only need to use 2 of them, but I know nothing on how to program them. I would assume a micro controller would be better but I don't know how to program it either, and I assume it's not as cheap as an EEPROM. I also have no experience in using an arduino. I do, however, know the basics of java, so if that helps please tell me

I really wanna do this. I've been thinking about it for quite a while. Please help.

    What you need is a switch or a multiplexer, providing your signals are logic levels, this should work

    I did think about that option during a break between my classes. The problem is that I will need a lot of them to switch all 60 signals at the same time, and I need it to be as small as possible

     

    Are the 60 switches all controlled separately by push buttons? Will you be switching more than one at once? When you say that you are switching signals are they digital or analog? Do the switches have to be bidirectional? B to D only , D to B only or both ways? When you say that you are connecting point B to D does this mean that you are disconnecting it from A at the same time? Does this mean that the signal from C is also switched to A?

    I made a little animation to help describe what I'm trying to achieve (hope it helps!)

     

    Note: I left two pins on both controllers disconnected as I think they will be connected to the switch. Meaning that each controller will have 32 pins. Do they make controllers with that many pins?

     

    EDIT: I forgot to mention that the signals are digital
