Based on previous blog diagram, i have a lot problem how to manage the process of this project. As example from previous blog diagram i use a ADC this project. We already know the function of ADC to convert analog to digital. so it is a big mistake for my project because on this project we did't need the digital converter. But we just need to rectifier circuit because to make a current from piezoelectric sensor flow in one direction and to prevent the flow current back to piezo sensor.
