I'm new here and I'm getting started with Arduino. Actually I'm a complete stupid in electronics. But I want to learn this stuff.
For an EL-wire project I need to control 12 EL-wires with 6 push buttons.
I'm intending to buy an Arduino, Protoshield and a mini breadboard (all portable). This is the scheme for the push buttons that I made, can someone please tell me if this will work? I need to know if it is possible before I go out and buy all the stuff I need....
Yeah, I understand what you mean, but I can't figure out all those symbols because I have no electrical knowledge at all. Then I would be changing symbols constantly before I have the right ones.
That is why I tried to make a schematic drawing of how the actual wiring would look like on the breadboard....
Like a simplified picture....
:~
Maybe this explanation makes it more clear?
While it is clear what you are trying to do you have to understand that a physical layout diagram is almost totally useless in assessing all but the most trivial of circuit.
There is no way anyone can see how this intergrates and interconnects with the rest of the system.
You need to learn how to read and draw schematics, no software just a pencil and paper will do, photograph it and post your results. This video is a good start to learning.
Just like visiting a foreign country, learning to read and then write the language enables you to communicate and that is the first step into learning.
Okay, did some research and made a sketch with electrical symbols.
It should represent a scheme with 6 push buttons on a mini breadboard. Connected to an Arduino via the 6 analog pins (set as digital in).
The output is via digital pin 1 to 12. This part of the project I already figured out.
Why use the analogue pins this would work just as well with the digital ones.
I am not a great fan of putting the +5 to a switch and have a pull down like you have. I prefer to have the switch to be between the pin and ground and either have the 10K pulling up to 5V or not have the resistors at all an enable the internal pull up resistors.

Thank you!
I use the Analog pins because I need 6 push buttons (and there are 6 pins) and I need 12 outputs to EL-wire (and there are 13 pins). Just to keep things clear and logical for me.
I will look into those resistors! What I found till now is that the internal pull up resistors are connected to pin 1-13. I need these for the output.
What I found till now is that the internal pull up resistors are connected to pin 1-13.
No they are fitted to all pins.
The analogue pins can be used as digital inputs, just call them pins 14, 15, 16 .... for analogue A0, A1, A2 ....
A digital read is much faster than an analogue read.
