Try Taifun's Camera extension.

The correct extension is Flashlight extension  https://puravidaapps.com/flashlight.php  and assumes your device actually has flashlight hardware.

However it might not be possible to do what you want Fernando ...read this about conflicts between using the flashlight and bar code scanner  https://groups.google.com/forum/#!topic/mitappinventortest/Dxz04KfdIsg

We want you to have fun with App Inventor so here are some resources to help you learn to use the AI2 tools  A very good way to learn App Inventor is to read the free Inventor's Manual here in the AI2 free online eBook   http://www.appinventor.org/book2 ... the links are at the bottom of the Web page.  The book 'teaches' users how to program with AI2 blocks.

There is a free programming course here http://www.appinventor.org/content/CourseInABox/Intro  and the aia files for the projects in the book are here:  http://www.appinventor.org/bookFiles  

How to do a lot of basic things with App Inventor are described here:  http://www.appinventor.org/content/howDoYou/eventHandling  .
