Serial Communication - Sensors

Which type of sensor is the TMP36?

• Motion sensor

• Temperature sensor

• Pressure sensor

• Sound sensor

What happens to the resistance of a photo-resistor when exposed to bright light?

• Increases

• Remains constant

• Decreases

• Becomes unpredictable

On an Arduino board, which pins are typically used for analog input?

• Digital pins only

• Any pin can be used

• Analog pins

• Requires a special shield

How can the code differentiate between a high and low temperature reading from the TMP36?

• By directly comparing the raw values

• It cannot differentiate

• By converting the raw value to a temperature scale

What can be used to display the sensor readings in Tinkercad?

• Only on a physical circuit

• Serial monitor

• By changing LED brightness

• Requires a separate software

In our last project, a higher photo-resistor reading likely indicates:

• Darker environment

• Brighter environment

• No change in light

• Sensor malfunction

How can the code be used to control an output based on the sensor readings?

• Not possible with this setup

• By using conditional statements

• Requires additional hardware

• Sensor data is for display only

What is a common application for our last project combining TMP36 and photo-resistor sensors?

• Controlling a music player

• Automatic light control based on light and temperature

• Detecting object movement

• Measuring sound levels

Troubleshooting Tip: If the sensor readings seem inaccurate, what should you double-check first?

• Arduino code logic

• Serial monitor settings

• Sensor connections to the Arduino

• Browser compatibility

Tinkercad allows simulating the circuit before building it physically. What is an advantage of this?

• Saves time and components for testing

• Easier to share the project

• You can securely simulate your project

• All answers are correct
