Hello,
I have a very general question concerning digital electronics:
Given a sinusoidal voltage source (followed by its rectification circuit so that in the end the voltage is constant) and a final sensor (to be powered directly with the voltage source), why do I need to put a microcontroller between the two systems (between the voltage source and the sensor)? I guess the microcontroller drives the sensor with specific requirements (voltage/current)? How does it do that more specifically? I hope I made the question clear...
