    Im getting more in to electronic and stuff. I made a mouse auto click by it self with a 555 timer now I'm trying make a LED flash with a 555 timer. But I'm having hard time reading the diagram. Could someone please take look at it and tell me If I got this right?. Added a attachment of my photo I made on paint. Here is also the place I got my information from http://www.555-timer-circuits.com/flashing-led.html

    -Thanks

    a few things wrong there.
    first of all your LED is connected to pins 1 and 8, their schematic clearly shows it goes on pin 1 then to a diode then pin 3.

    actually after a really close look the diode seems to be bout the only thing wrong

    resistor come from pin 3 to pos side of LED then goes to pin 1 the neg side of the cap and the neg side of your battery.
    now from your drawing it appears as though you connected your LED straight to the battery, so I am assuming it is no good now, try another LED

    Alright then, All I have to do is move the LED around and everything else is alright?. Also haven't made this thing yet so everything still in good shape.

    kk
    from what i see thats all you need to do.... let me know how you go
    have you got a breadboard to try this on? it might help alot

    Almost any LED will work with this.

    Having placed it across the power supply, you may have damaged it in any case.

    I went to a store that sells electronics and guy there looked at my drawing/other one and he said everything looks alright but one 1k resistor isn't. Here update drawing of my thing im trying make can you all please take a 2ed look at it? Here link to ithttp://tinypic.com/view.php?pic=2m3o1fl&s=6

    you still dont have the 1k resistor on the left side connected correctly

    it should be between pin 3 and the LED

    can you see the difference to what you built compared to the schematic ?

    you will get there :)
    ..... but you need to learn to more closely follow the schematic and transfer that layout to the physical layout

    Alright remade my whole drawing is this right now? http://tinypic.com/view.php?pic=33xu5cg&s=6 And Do I really need wires going from 2 to 6 and 4 to 8?
    Also do you know any web sites that would help me understand the schematic and the other stuff more?

    does the schematic show those wires ?
    YES

    then you need them :)

    and yes ... overall it looks good

    ok now I am interested... how did you hurt yourself?
    also try getting a breadboard, once you figure out the pathways it will help you out alot. figuring out where the wires go is the MOST important part besides being safe.

    Congratulations :)

    It's always good when something you've built starts to work.
