Chapter 8 Challenges
Questions
- What would the relative sensitivity of the IR detector be if you use tone to send a 35 kHz signal? What is the relative sensitivity with a 36 kHz signal?
- What keyword is used to declare a constant?
- What statement is used to sweep through the list of frequencies used for IR distance measurements?
- What’s a summing junction?
- In our closed loop proportional control block diagrams, what two values are used to calculate the error term?
- How do delays in the loop function contribute to setting the sampling rate?
Exercises
- Write a segment of code that does the frequency sweep for just four frequencies instead of five.
- Write global constant declarations that initialize kpl as –45 and kpr as –55.
Projects
- Write a sketch that allows you to hold your hand in front of the BOE Shield-Bot and push it backwards and forwards with no turning.
