Probably it is a stupid question but I am really a total idiot in electronics!!!!
I have some projects with Arduino that will use only LEDs to light starship miniatures (windows, navigation, etc.).
I already have a small prototype that I just started working on:
My problem is that I don't know what gauge of wire I should use for the actual circuit. The LEDs will be soldered directly to the tip of the wires and these will reach the lighting places in a harness.
I have found a virtual store that sells plastic insulated wires in the following gauges: 0.05mm; 0.10mm; 0.13mm; 0.20mm; 0.30mm; 0.32mm; 0.50mm.
What would be the ideal gauge for such application? I thought on buy the thinner one (because LED has a low consuming and also because it's cheaper!) but better to ask first.
I will use also some high brightness white and blue LED tapes but these ones I will attach directly to the power supply (no arduino). What wire gauge in this case?
To give you an idea about the type of wiring I am talking about, here it is an example of a similar project:
And here an example of the project after done:
