Problem 3: Interfacing Circuits (10 points) You are concerned about high voltage noise (+ 5VDC to +20VDC ) on a digital input line to your microcontroller. Use all the following four circuit protection elements from the list below and assemble them in a circuit diagram to protect your microcontroller's digital input 0 (DI 0) from "getting fried" by the high voltage. Note DGND means "digital ground". Don't forget that you can rotate elements as needed
