Which of the following describes a piezoelectric sensor's primary method of operation?
Question 2
When interfacing an analog sensor with a microcontroller, what is the primary reason for using an Analog-to-Digital Converter (ADC)?
Question 3
A stepper motor is commonly used in applications requiring precise positional control. How does a microcontroller typically control the angular position of a stepper motor?
Question 4
Consider a scenario where a Hall effect sensor is used to detect the presence of a magnetic field. If the sensor outputs a digital signal, what does a 'HIGH' (e.g., $5 \text{ V}$) output typically signify?
Question 5
Which of the following is the most critical consideration when selecting an actuator for a system that requires very high force output and slow, controlled movement?
