[Problems with my 555 circuit]

Ok well here is the picture of the circuit im doing exept i didnt put the 680R resistors in when testing it out...

Ok so me not having resistors in series with the LEDs could be whats stopping it from working?

None of the rails on my strip board are touching but still i have the same problem it just stays on and i am using a 10uf capacitor.

Will adding 680R Resistors In series fix the problem?

Sorry for double post but if i connect a LED from pin 3 to the plus it flasghees but really fast. And if i connect it from pin 3 the Negative ti just stays on. ill see what happens with both at asme tie and ill edit the post.

Yeah so if i reverse the capacitor (which im doing now i just plugged in my soldering iron.) it should flash?

Ok well ive put in an offer on ebay for some 10uf ones. so will this fix what is wrong?

Thanks so far youve been a great help!  ;D

Ok well i bought some 100uf  onces from ebay lolb ut only cost 2.95 (well i didnt the person im making them for did.) i won tell them and i will buy some 10uf ones. Also can i not use a variable resistor?

You guys hgave been the best out of all the electronic forums ive posted on!

thnx alot

[Problems with my 555 circuit]

Hi well basically i have a hobby in RC cars. A few week back i started to make circuits using the 555 timer but now i want to make them on board. i have cut some board and have soldered all the components on. the only change ive made to the circuit is a 100uf capacitor instead of a 10uf one. the circuit does nto seem to flash the LED. it simply just stays on and i checked everything and no legs touch and everything goes where it should any ideas? 

i dont know if this is in the right section but i saw somethign else about a 555 here so i posted it here!
