LED Circuit

[buttface96]

Okay im a ..::n00b::.. whennit comes to what i wanna do, so i need ur guys help. Basically Im making a 8 Led Chasing cicuit, i saw ur guys diagram for 10 leds http://www.electronics-lab.com/projects/motor_light/028/ <----There and i was wondering, can i use those same parts to do an 8 led circuit, or would i have to replace a few parts with different ones to do 8 instaed of 10. Thanx guys!

buttface,

You can build it in many different ways. Here is an example with 6 LEDs.

Okay I think i get5 the poitn og making an led circuit but i still have a few questions:

1. For the 555 timer do i need to get a 8 or 14 pin
2. What kind of wire should i use?
3. What is the clock for, and what is it called?
4. Can i get all of this stuff at radioshack?

Okay now i have a new problem... TIME. I need a circuit installed by Thurseday. Is there any place i can buy a led cicuit board? I know xoxide does, but there shipping is killer. $10 standard shipping for a small pcb board with circuits. Anyway i need Help ASAP thanx!

Why not make your own circuit board with either perf board or using one of the kits with etchant? If you are in a great hurry, perf board would be a good way to go. You could use wire wrap to make your connections.

I Need a 12v version of this.

Hotwaterwizard,
The knightrider circuit will work fine on 12V.

I know where this circuit came from ;D

I've build the above circuit, and has nothing to do with Knight Rider KITT scanner.

Check the little trails that is left behind, maybe if you put a 10uF to 100uF eletrolytic capacitor to slow down the discharge of the LED lit, you could get the same effect.

Wellington,
I know that place, it is a great University.
