How do I use a timer to turn LEDs on one after the other? Answered

I need to find a way to have a series of red LEDs turn on one after the other, as if it was a snake, moving along a line, or a laser pointer, slowly turning on, the lights being the laser beam... How would I do this with basic circuitry knowledge and a tight budget (less than 20 dollars)?

Here is a simple circuit 4 U


And if you want sequential light up.


Is there anything simpler or a kit I could buy? I have extremely basic circuitry knowledge, and frankly, I don't know how to read schematics. I know it sounds bad, but it's true...


Simple and Works!
You can do knight rider lights as well with a bit of rearranging of the LEDS.
