this is my first post cause i´m totally new in the arduino world.
the reason for this is that i would like to achieve a small project,
where i was told that a arduino could help me to achieve that.
so maybe you could assist me in the first time? would be great !!
so, to begin i use Arduino Mega 2560 cause it has so many pins,
that i could use for.
what is my goal:
i have 4 wires (1-4) with +5Volt for 16 wires (5-20) to be closed together just a mini-second like buttons
depending on different combinations.
value (1,5) = connection wire 1 (on PIN1) with wire 5 (on Pin5)
value (3,6) = connection wire 3 (on PIN3) with wire 6 (on Pin6)
and so on...
what i have done till now is i have connected the 4 +5Volt wires to the digital pins 30-33
and the rest of 16 wires to 34 till 49.
Now my question is, how to get the connections done?
would be great to get our help !!
