This is an animated drawing of a waveform from a dimmer switch. It is useful in visualizing how an AC Dimmer works. Many other things use this chopped waveform like variable speed drills. This simulates what you would see with a digital oscilloscope.This version features a transparent background, so it will look good on most sites. Like all drawings I create it has an optimized file size for minimal bandwith usage and uses only web safe colors.
