what does "+5 v with an arrow" mean ? Answered

I am building an arduino by myself using the schematic as the board isnt available in our country. The problem is that i dont understand one thing in the schematic. Its an arrow pointing upwards with 5v written next to it. I am a beginner.Your help will be greatly appreciated :D

To add to all the correct stuff the other s said, it's kind of counterpart to the ground symbol (the up-side-down T).

It is just easier to use this symbols instead of cluttering the diagram with continuous power and ground lines.

If you build the circuit, make sure you connect all GND points, all +5V points and so on.

More basically, the arrow with a label is a (very informal) way of saying "connected to something somewhere else". The arrow is actually unnecessary -- a labelled line is sufficient -- but some folks use it for emphasis to make these named connections more visible. Others use other symbols for the same purpose (drawing a distinction between on-page and off-page connections, for example)... but usually a single wire going to text can be assumed to be a named connection of some sort.

Every one else is right )of course) but for clarity circuit diagrams often miss off the supply line and the ground line for clarity and use the arrow & label instead.

+5 v is an indicator for postive 5 volts, and the arrow indicates that this is most likely to be connected to the power source (i.e. of 5 v. the positive terminal).

It means that that line connects to positive 5 volts.
