  1x 555 timer
  1x LED
  1x 9 volt battery and clip
  1x 220μf capacitor
  1x 101 Ω resister
  1x 101 Ω variable resister
  1x 900 Ω resister
  multiple wires
  breadboard

need a bigger schematic cant understand a thing

Whats That a Picture(s) of???

Look thanks for posting this BUT:
You really are not helping folks with the poorly drawn circuit diagram, it's almost certain to create avoidable mistakes.
Also 9V batteries are not cheap & most LED lights that I come across are typically 1x AAA or 2x AAA, IE 1.5 or 3 V.
I was thinking about using this on my bike but the voltage is so high I am dubious about the likelihood of either over-driving the LEDs or just wasting power in creating the necessary voltage drop.
Can you spell out the reasons you selected 9V please.
Thanks

i had a lot just lying around the house, you need at least 5 volts if not using a CMOS 555 chip.

[Sunbanks]

Instead of using a 9 volt battery could you use three 3 volt batteries? 

[far.peter]

yes, it just needs to be at least 5 volts.

[far.peter]

mistake, you cant, but you can use 4 AA batteries

[far.peter]

i must have been tired, you can :)

 Help! I need to use this circuit for a project. My led blinks too fast! I am using just a 100 ohm resister instead of a  variable resister. Is there something that I should change??? thanks

[far.peter]

use higher resistance

[shadowkiller]

 Thanks!!!!

Good, but this will be better if you'd change the word resistor to resistor not resister and if you'd have better pictures. And I personally would rather open and instructable spelled with a Big letter in the beginning of the name than with small letter. Okay that's me: D The schematic could also be drawen with computer. Sorry for all that nagging : D Good instructable, will really help someone who is starting with the 555s

[Jodex]

Just some tips=)

[far.peter]

thanks

i dont remember what the board your using is called.could you plz tell me

[far.peter]

Its a breadboard, I got it from Abra Electronics.

[far.peter]

sorry, i didn't have my tripod.

Any chance of images in focus?
