Is it possible to use more them the 6 analog inputs available in the board? I mean, can I use any sort of electronic circuit component such as a multiplexer to extend the number of analog inputs available? (I may need that)

Sorry for not having searched appropriately. (I'll try to search for the appropriate keywords next time)

Thanks for the help

I have a small (primitive but working) PCB design for 2 4051 IC's giving 16 analog inputs at the expense of 3 digital pins + one analog.

You can find it here:

I used it for reading 16 slidepots. The Arduinocode for doing that and sending the values to a PC is included in the zip file.

Thanks for the attention...

I've already downloaded it from the other forum link that mem posted (I think it was you who posted it in the other forum link  :))

I'll try to make it work

Anyway thanks for the help
