Vehicle Sound Effect System

I'm a technical educator developing and sharing electromechanical projects.

This is a sound effect circuit for multiple purposes one of which is to act as a turbo blow off sound effect circuit for vehicles. IT can be used for many other purposes like robotics, answering products etc.

100 different sound effects stored on a mp3 module are managed by the pic microcontroller and played according to given inputs.

thanks for your sponsorship. Here are some videos of the first prototype working.
