Can matrix keypad be used?

[Mridul Agarwal]

Hi,

I have posted my questions for my project but I hope this is the last one.

Can I use matrix keypad as input in a circuit as well as in a progrmme which uses mobile as its input. I mean to say which uses mobile frequencies as its input.

Hi Mridul,

I think you must modify your code and your hardware accordingly.
