Topic: How to assign multiple functions to one button for arduino 4*4 matrix keypad (Read 174 times) previous topic - next topic


I want to assign multiple functions to all the keys in 4x4 matrix keypad
For example if the button 1 is press and hold for more then 2 second it should print G,  for button 2 = M, and so on,
Else it should print assigned value
Please help
I am very new to programming
Thank you all in advance


There are many forum threads dealing with 'long press', you should find some guidance there.  Some libraries also include this functionality.

My MD_UISwitch library has examples for using different types of keys. Key matrix is one ofthem. If you are interested https://github.com/MajicDesigns/MD_UISwitch
