problem in my arduino tester project

juanjocal · April 25, 2022, 6:48am

hello, I have a problem in my programming, the thing is, I am making a tester of different cables with their respective pins, I have different connectors ready to be connected to test each cable, this project has a menu to make it more intuitive, Getting to the point, the problem is that I am giving 5 volts to the output and reading the input to see if there is continuity, I would like to know how to differentiate between the pins, sorry I am new to this, thanks in advance. (I leave the program).

#include <Wire.h>
#include <LiquidCrystal_I2C.h>

LiquidCrystal_I2C lcd(0x27, 20, 4);

int upButton = 11;
int downButton = 12;
int selectButton = 13;
int menu = 1;

                    
//SINGLE
const int pin1entradasingle= {9};
const int pin1salidasingle= {4};
const int pin2entradasingle= {8};
const int pin2salidasingle= {3};
const int pin3entradasingle= {7};
const int pin3salidasingle= {2};
const int pin4entradasingle= {6};
const int pin4salidasingle= {1};
const int pin5entradasingle= {5};
const int pin5salidasingle= {0};
//STRIKE
const int pin1entradastrike= {34};
const int pin1salidastrike= {35};
const int pin2entradastrike= {36};

Hello juanjocal
Generaly spoken:
Take some time, study the IPO model and take a piece of paper plus a pencil and design a program structure. Identify modules could to be coded and tested separetly. Merge after sucessfull testing all modules together to the needed project.
It is highly recommented to take a view into some powerful C++ instructions like STRUCT, ENUM, ARRAY, CASE/SWITCH,UDT, RANGE-BASED-FOR-LOOP, etc, too.
The ussage of the delay() function shall be not used to get the realtime behaiviour of the sketch.

Have a nice day and enjoy coding in C++.
Дайте миру шанс!

thank you very much friend, but do you have any idea or a little explanation about which variable to use to differentiate between pins

Search the forum for "cable tester" and find many such projects discussed and explained.
