What does GPIO stand for?
Think about the full form of each word in the acronym.
What mode would you use for a pin that reads a sensor's data?
Consider what type of action the pin is taking.
What is the primary function of a GPIO pin set to output mode?
Think about what output mode means.
True or False: Pull-up resistors can only be used with input pins.
Recall the function of pull-up resistors.
Design a simple embedded system using GPIO pins to control an LED based on a button press sensed by a GPIO input. Describe the setup and logic.
Draw a schematic diagram to help visualize your design.
