Reflections:

The project, although simple to begin with, required a lot of iterations  to make the sensor work correctly. What I assumed would be a straightforward program, became increasingly difficult with the addition of each element. The most interesting part was to make the sensor, LED, buzzer and push button work in relation with each other. The conditions needed to be precise to ensure that the LED and buzzer give the correct output.  It was interesting to relay the data via two outputs- one visual and one sound. The sensor was tricky to work with and needed quite a few adjustments to achieve accuracy.

In this project, the buzzer kept buzzing once it was triggered and would not stop unless the button was pushed. On releasing the button, the buzzer would go off again due to the first input.  To take this a step further, more functionality could be added if the buzzer could switch off on its own after a set duration. It would then be able to alert the user when motion has been detected again after some time.
