As we conclude, here is a list of questions for you to test your knowledge regarding this chapter's material. You will find the answers in the Assessments section of the book:
- When it comes to controlling a transistor, how do MOSFET and BJT differ?Â
- You are controlling a motor using a MOSFET, however, you switch off the MOSFET (for example, making the GPIO pin low), but the motor does not turn off promptly but instead spins down. Why?
- You have selected a random MOSFET that you want to control from a Raspberry Pi 3.3-volt GPIO but it does not work. What is some possible cause of the problem?
- Other than switching, what common feature do optocouplers and relays share that transistors do not?
- What is the difference between an active low and active high GPIO?
- Why do we prefer a physical pull-down resistor for the MOSFET's Gate leg over an in-code activated pull-down?
- For a DC motor, what does the stall current represent?
- For a DC motor, what is the difference between...
