Hello,
I really need a little help, because I don´t know how to do this. I have Arduino uno + TFT resistive touchscreen Adafruit ILI9341. I created areas on this display where every area has own number. It is like keyboard from 0 to 9. And now what I need. When I push for example button 1, 5, 9, 0, I want to remember this numbers and insert this numbers into one variable. So the resulting number will be 1590. Should I use for this array or something else? I am new at this.
Thank you very much for your help.
