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. ![mlkjgghcvjj (1).jpg](https://europe1.discourse-cdn.com/arduino/original/4X/f/7/1/f7167dbd534da190fa5ba35976ac71f985ff370c.jpeg) ---

Yeah... Whoever created that probably uses the same power-bus setup on all his projects. ---

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. ---
