In really old scanners you will normally find a florescent light source but new ones use a RGB light bar to shine on the document being scanned. There are lots of ways to make the thing light since it is a common positive 5 volt RGB light bar. To kick it up a notch Hack Shed decided to tie it into an Arduino and make it totally remote controllable. Watch the video below to see it in action. Check out the build details to get some inspiration and have a look at the code.Â
