looking for circut simulators

i am looking for any kind of computer program that can simulate a circut. so i can see how fast a light will flash or how fast a chaser circut will be before i build it

For example something similar to this

use Google to search for circuit simulator software.

What you want is SPICE, a circuit simulator programming tool.

A free version is called LTSpice, from Linear Technology (www.linear.com)

You will have to know basic electrical engineering to use it, which means to do what you want, you will have had to understand about junior level EE coursework in college.

Good luck!

I can Make simple circuits, and flasher circuits with a 555. I want to try to make a chaser on it but want to be able to make it on the computer and play with the R values to change and figure out the flash rate I want

If you know enough to build the circuit, you should be able to simulate it in LTSpice. It has a 555 model in the built-in libraries.

I use YENKA, it allows you to build and test circuits. I have used it to test
555 circuits for LED lighting. The test instruments work very well, especially
the O scope. I have now started using Arduino for my lighting. You can
make all kinds of LED circuits by just programming. They are really cheap,
about 2.50 and under.
