Prashanth,
Welcome to the Cayenne community!

I’m not sure where you got stuck. Could you provide what you did to get to where you are?

It is also helpful to know what version of Pi you are using (A, B, B+, 2b, 3b, Zero), and what operating system is on your Pi (Wheezy, Jessie (full or lite)), and are you using an internet browser or an app (Android, iOS).

Have a great day,

-Ian

Hi,

I’m using raspberry B, Raspbian OS, and internet browser.
Actually,I was able to print the number which is pressed on the keypad.
Now I want to take input from the keypad as password and check whether the
entered password is matching with the default password set by me. I’m
using 3x4 keypad.
Could u please provide me with the python programme for above task.

Thanks in Advance.

Have a great day!

It really depends on your keypad. You can try this thread: https://www.raspberrypi.org/forums/viewtopic.php?f=37&t=34235

Cayenne doesn’t support keypads yet so I would suggest asking this question over at the Raspberry Pi forums.
