Algodoo

There are a few scenes on Algobox that use PWM to control motors and other things (see s_noonan's scene called PULSE WIDTH MODULATION (PWM) as a good example), but until now, there have not been any scenes that explain what PWM is, and how it can be used. My scene is a tutorial that does just that. It's a little verbose, but I tried to explain as much about PWM as I can in such a small space. If interested to learn more, do a Google search for PWM on the web.

I hope you find this scene to be interesting and educational!
