App interface and usage


The buzzer can be turned ON and OFF.
Buzzer State


The buzzer once turned ON continues to be on till you turn it off using another instance of the block. So, if you turn it on inside a conditional block, it does not automatically turn off when the condition ceases to be true; you would need to set it off as part of the code in your project.


This project continuously checks the motion sensor to see if motion is detected. The buzzer is turned on if motion is detected.
