The Seven-Segment Display and the Stepper Motor

In this chapter, we will look at seven-segment displays and learn what they are and how they work. We will write a program to control the display on a single seven-segment display and then move on to a program to control a collection of four seven-segment displays. We will learn about the timers in a PIC and how to use them to create a variable delay. We will then move on to look at a simple stepper motor and write a program to drive it clockwise and anticlockwise. After reading this chapter, you will know how to use a delay and how to control and use a seven-segment display and drive a 5V DC stepper motor.
