Abstract

 We presented in that work a project for computation program built in Visual Basic VB and whose purpose is to do the synchronization among a video file, an audio file and a system of controlled illumination. The circuit for controlled illumination is composed by a group of issuing cannons of light of the type PARLED36 worked through the input door USB of a computer through a serial signal of the DMX 512 protocol. That configuration allows that the computational Program can be used to produce simultaneous information among video, sound and illumination with different colors, different intensities and several sequential manners. We presented an application of the Software built in a Model for education ends where it is obtained a perfect synchronization between the illustrative images and audio with narrative text in synthon with the control of 25 cannons PARLED36 with 5 channels of different from colors that play lights in sites or objects of interest. In that application the Software works as didactic tool. The functional characteristics presented by the Software indicate it for other applications where there is need to synchronize events, as, in cultural displays, fashion parades, theatrical shows or even in systems of robots' control.
