Must answer all the questions.Dont attempt only one.i will dislike otherwise. Please help answer the following question regarding the PID controller. a) Define the meaning of the term "offset" b) Explain how offset can be reduced by adjusting the proportional action of controller c) State why (b) is not the best way of effectively dealing with "offset" AND Explain how "offset" can be reduced to zero.

Which of the following are part of the Arduino microcomputer. The answer could be more than one

A common objective when manufacturing printed circuit boards (PCBs) is O a. maximizing the number of drill bit changes. O b. maximizing the number of holes drilled. c. minimizing the total distance the drill bit must be moved. O d. minimizing the number of holes drilled.

Q4 Table Q4 shows the mode and task that need to be implemented using PIC18F452. (a) Mode Switch (SW1) 1 Press 1 time 2 Press 2 times Table Q4 Task Move the LED right to left and continue back from left to right. Control the duty cycle of PWM for the period of 2 ms. You are given 1 switch, 1 potentiometer and 8 LEDs, sketch the interface between the components and PIC microcontroller. (b) Construct a C18 program to control the tasks in Table Q4. (4 marks)
