5 cards from this section. Quick, good the night before a test.
What is the purpose of data pins in an IoT system?
Think about what connects the sensor to the microcontroller.
Name the two types of pins used in data transmission.
One sends simple signals and the other reads voltage.
What function is used to read voltage from an analog sensor in Arduino?
Think about how voltage is measured.
True or False: Digital pins can only send binary signals.
What type of data do digital pins communicate?
Design a simple IoT weather station and describe how you would connect the temperature and humidity sensors to a microcontroller. Include the types of data pins you would use and the code initialization.
Think about how each sensor communicates with the microcontroller.
Explain how you would troubleshoot a situation where a sensor does not provide the expected data to the microcontroller. What steps would you take?
Consider the flow of information from the sensor to the microcontroller.
