Using Arduino Programming Questions

Hi there, i need some help in this SelectionList sketch from oli kraus. I tried use just regular tactile switches with a 10K pulldown or pullup resistor but it didn't work out for me. i use a Mega2560 Pro Mini from epalsite. it would be nice if somebody could help me. thnx

It would be nice if someone would simply post their code.

Please post the code that you tried

Its the code up there. like i said i tried with 10k pull up and pull resistors it didn't work. But strangely it worked with this keypad

4x4-Matrix-Keypad-Keyboard-Tastatur-Modul-16-Tasten-8-LED

but only the red keys which is pulled down by 10K resistors and connected with red LED's. I just wanted to use it with 4 keys for my project. I was going to make first the buttons work then modify the code for my needs.

As far as I can see the code that you posted does not read any input pins either singly or from a keypad. Can you please explain where in the code they are read ?

I actually have no clue how Oli did this..lol, but it works flawlessly on the keypad.

now I uncommented this line and tried this.

// U8g2 SH1106 Proto-Shield
u8g2.begin(/* menu_select_pin= / 2, / menu_next_pin= / 4, / menu_prev_pin= / 7, / menu_up_pin= / 6, / menu_down_pin= / 5, / menu_home_pin= */ 3);

and it works with the following pins 2,4,7,6,5 on the keypad as well.
