Hello everyone! I'm new to this so please bear with me. I have been working through an Arduino beginners kit I got for Xmas and now want to try something for myself.

I'm wanting to display a two digit number on a double seven segment display. The input is from a 3x4 keypad. I'm wanting to input two digits then press either # or * to confirm the number and then have it display. I'm happy with using the keypad and the seven segment displays separately but I'm struggling to combine the two. I'm also looking at using a piezo to ring an alarm once the numbers are displayed.

Any suggestions please?

Welcome!

Are you saying that you have successfully (a) read the keypad, and (b) displayed numbers on the seven-segment displays, perhaps as separate sketches? It would help if you'd be more specific about the difficulty, and also post your code.

Use the "#" button to insert "code" tags, paste the code between them. Makes it easier to read.

Sorry, probably not as clear as I thought. I'm happy using the two components as in using the beginners sketches for each.

What I'm wanting to do is input a two digit number and display it on a double 7 set display.

So for example input an integer from 00-99 and have it displayed

I haven't written any code as yet, still learning.......... Just wondered how to take the input and convert to a form suitable to output.

Hope that makes a bit more sense.
