lack of input pins

[iceman83]

hi, I am working on a project and I have a problem. a microcontroller has to take 24 inputs simultaneously from 24 sensors but the microcontroller does not have enough input pins? how can I solve this problem?

Use a larger micro-controller :lol:

But that's just one way, you can use port expanders to give more inputs (basically shift registers). A lot though depends on EXACTLY what the sensors are, and how you need to read them.

But in all cases 'simultaneously' isn't possible, but a microcontroller can usually do it more than fast enough to make it appear simultaneous.

What kind of sensors? maybe you can.
