8.7. Interfacing Sensors and Actuators with Microcontrollers

Try these first

1. 1.

   What does PWM stand for?

   Hint

   Think about how we control the power sent to a motor.

2. 2.

   Name one type of pin configuration for sensors.

   Hint

   Consider the types of signals they handle.

3. 3.

   What does PWM control in an actuator?

   • On/Off state
   • Speed
   • Color

   Hint

   Remember how we can modulate power output.

4. 4.

   True or False: Interrupts allow for continuous monitoring of sensors.

   • True
   • False

   Hint

   Recall how an interrupt functions.

5. 5.

   Design a simple robot that uses a microcontroller to avoid obstacles. Describe the pin configurations and code logic you would implement.

   Hint

   Think about how you would connect the sensors and list specific functions required.

6. 6.

   Suppose your microcontroller is not responding to interrupts consistently. What could be the potential issues, and how would you troubleshoot?

   Hint

   Think of factors that could affect the electrical and software performance.
