You have an application where you need to control a DC motor using an Arduino microcontroller and a BJT. The motor can be modeled as a simple 40 2 resistance. The motor is powered by a 5 V DC power supply. Answer the following: a. Show a schematic of the circuit you will use to control the motor. b. Calculate the resistance value needed for the current-limiting resistor connected to the transistor. To do this, use the criteria discussed in class to ensure that the transistor is operating in saturation mode (i.e., fully "on"). c. What resistor would you actually purchase to build this circuit?
