Problem with entering the code on the 4x4 membrane keypad

niejestempro · September 15, 2021, 1:27pm

Hi. I am new to your arduino world. I used to play something with arduino, but I don't remember what and how.
Also sorry for my English, it may not be very correct.

Well, I have a problem with entering the code to arm and disarm in two game modes "search and destroy" and "sabotage". The problem is that I can only enter the numbers 3,6,9, pressing the remaining 1,2,4,5,7,8,0 nothing happens. I used code from the Keypad library, set my Connect Pins in code and all buttons work. There is clearly something wrong with this code, I just don't know what.

Of course, I found the project ready, I edited only the most necessary things. Has anyone been able to help me with this problem? Thank you in advance for your help and please be understanding.

Which board? On a 328P based board (like an Uno, Nano and ProMini), A4 and A5 (that you use for your keypad) are also the I2C pins.

You might have a similar conflict with other boards.

niejestempro · September 15, 2021, 2:01pm

Arduino UNO R3. Yes, I am using an I2C converter. So the best solution is to desolder it and leave the screen alone? Can there be any other way around it?

EDIT. I changed A4 and A5 pin to 10 and 7 pin. Keyboard now works fine. Anything else I should know?

sterretje · September 15, 2021, 2:10pm

Great. I was just looking at your code to see if there were free pins

No idea.

niejestempro · September 15, 2021, 2:19pm

Thank you really for pointing me to the solution. I will close the topic behind it, could you tell me how to check which pins are still free (or what pins does I2C use because I have other pins declared) in a given project? Just for fun I checked 0 and 1 pin, unfortunately it didn't work

However, the arduino tutorials in my language are incompetent or I missed / misunderstood something

Railroader · September 15, 2021, 2:57pm

Free pins? I would read the code and collect the used pins. Then the other ones ought to be free.

alto777 · September 15, 2021, 3:20pm

No surprise there, 1 and 0 are used for serial communication over the USB and with the serial monitor in the IDE or other PC terminal,program. Best to avoid.

You've already bumped into SCL and SDA at A5 and A4, if you need I2C you can't use those.

There are pins used for another control mechanism SPI, 10, 11, 12 and 13. Use those last or be prepared to move out of the way if you need SPI for some device you attach.

I avoid 13, unlucky number. No, I avoid it because it is the build in LED on the board so can act not quite like another I/O pin - rather than worry about it, use it later rather than sooner.

The A0 and up pins are for analog input, but they work just fine as regular digital I/O pins.

Each Arduino variant has a similar list of pins, google is your friend here now that you know what to look for.
