Raspberry Pi For Beginners - 2022 Complete Course - Activity 08 - Solution

The video tutorial explains how to power an LED using a motion sensor. It covers setting up the code to print sensor output, configuring the LED, and implementing logic to control the LED based on sensor input. The tutorial also demonstrates running the script and discusses potential issues like false positives and sensor quality affecting performance.

What is the purpose of the initial setup in the script?

• To print the sensor output every 0.1 second

• To create a new sensor

• To delete existing code

• To change the sensor type

Which GPIO pin is used for the LED in the setup?

• Pin 20

• Pin 19

• Pin 18

• Pin 17

What condition is checked to turn on the LED?

• If the sensor input is high

• If the sensor input is low

• If the LED is already on

• If the LED is already off

What might cause false positives or negatives in the sensor readings?

• Environmental factors like light and wind

• The length of the wires

• The color of the LED

• The type of power source used

What is the observed behavior of the LED when motion is detected?

• The LED changes color

• The LED turns on

• The LED turns off

• The LED blinks rapidly
