Will this circuit work?

  1. Hi,
    i was wondering would this circuit work? don't want to buy a 100 buttons if it's not going to work as i am cheap and lazy :)

    Thanks,
    Jamie

    hi ya Jamie

    no it wont, because you only have one side of the battery connected
    and ALL legs of the LED's etc are connected to that one power rail

    This is what you have .... see the problem ? ....

    Schematic circuit diagrams are much more useful than quasi pictorial diagrams. It's a good idea to learn to use schematics as a matter of course. If someone is not planning to use breadboard, then they need to translate twice and the symbols can be a bit vague if you don't stick to the rules.
    It's a bit like showing pictures of piles of beans rather than using numerical symbols, to describe an arithmetic operation.

    Dave has demonstrated very well, how to do the 'properly'.

    Jamie,
    can you now take that circuit I have shown you and transfer it to your breadboard ?

    have a go and show us a pic before you put power onto the board so we can make sure its OK :smile:
    Make sure you have the LEDs orientated the correct way

    cheers
    Dave
