Q5. (a) An embedded system is to be designed to run from battery power. The system must remain powered, but will have short periods of activity, separated by long periods of inactivity. Describe in detail the two essential components of power consumption in an embedded system [04 Marks (b) With the aid of diagrams explain the operation of an RC servo motor. [06 Marks] (c) With reference to Figure Q5(e) answer the following questions: () Describe in detail the PIC16F887 connections to the stepper motor. [04 Marks) [06 Marks] (ii) What is the purpose of the IC placed between the microcontroller and stepper [05 Marks (ii) Write a C-code to rotate the stepper motor in clockwise direction. motor? Suggest an alternate device to ensure smooth running of the motor. 4,7 4.7 4.7k 4.7k Uipolar Stepper Moto PIC16F887 MICROCONTROLLER +5V Figure Q5(c) Q5.
