Great program and very useful. But he was wondering if we had anymore breadboard diagrams like the ones the admin and I were making.


No, those diagrams are from this site specifically. Look at the bottom right corner of all the diagrams. Notice how they say 555-timer-circuits.com? That's because they originated from here. The admin made a thread that has all the components for download and viewing here. It's where I got my images so I could make my own diagrams. You're going to have to get somebody to make them, or make them yourself, if you want any more. I haven't really made any recently but I can tell you how to make them. Simply copy, paste, rotate, and label the components in the appropriate places on breadboard image (It's useful to have multiple layers) so that you have a complete diagram that is to scale and accurate. I use Paint.Net for my diagrams and I may do a video tutorial with an example within the next couple of weeks, depending on my schedule.

Yes , I could copy and paste if I knew the slightest thing about circuits lol. Thanks for the help guys but I am a complete noob at this and unless I have a picture hildng my hand the while way I don't think I could do it. I need alt more practice first

I built this circuit (Knight Rider) following the instructions in the video - it worked but the LED's were very dim and the sequence very slow... I replaced the 3.3microfarat with a 1.0microfarat and it seems to work just fine... Any reasoning behind this?

Do you have another circuit in mind that you would like one of these breadboard drawings done for? I am sure someone here would be more than happy to make one for you. I will if you want but due to some other projects I am working on right now it might be a day or two, let me know.

What were you using for power supply, batteries or plug in? Could be low voltage.

Hi George,
Thanks for the reply... I am using a 9 volt battery at this time... I'll give it another try with the 3.3 when I get a 12v power supply - either 4 bateries or a wall wart...

Hi,

I would like the LEDs to fade out right after they are being lit. I would have though that placing a capacitor before or after the resistance in parralel to the LED with a rectifier diode right after the output of the 4017 would have done the job. I've tried with my spare 3.3uf but it does not work. LED turns off right away.

I've tried it with a simple AA batt with a red led, 3.3uf and I was satisfied by the result. Why it's not working in that circuit?


Thanks guys!

Below is a link to my result. I've got some pots on the way to replace R2 so I can speed up the timer or slow it down. The next iteration of this project for me would be fading each LED out after it is flashed as the knight rider car actually does. As a EE student at SPSU I'm sure it's only a matter of time before I'm able to do that in my sleep but for now I'm just in EE1000 (intro LOL)
