hello everyone ,im very new to arduino im trying to set very simple circuit, i found one on internet , i didnt understand the red cable of 5v and its role in the montage.
Yeah... Whoever created that probably uses the same power-bus setup on all his projects.
thank you guys
OP - as you become more familiar, explore your future options for circuit diagrams.
I won't suggest one in particular - there are many options - all promoted by various people om the forum!
The Fritzing diagram used in your example is often used by beginners, but is severely limited in its usefulness beyond a blinking LED or hooking up a 9V battery. You'll often get negative feedback when you use a Fritzy - from me as well!
Schematics are a bit like text cut & paste - mistakes can creep in, so it's better if you draw it yourself, then you know and understand why it's drawn that way.
:o Not a Guy!
You look like Batman.
Oh, we had this conversation already
