I am making a proof of concept work for my studies.
I was looking forward in using a 16x2 lcd, an SD card, and a 4x4 keypad and some other components tha only use 1 input such as (125khz rfid, and a buzzer).
I have some doubt regarding if the inputs for LCD SD and keypad will be enough.
I have used all of them separately, but I am afraid the libraries will use the same pins, is there a workaround here?
