When thinking about this assignment I wanted to do something that was kind of relevant to stuff going on today(Covid-19) and low and behold I found this video of a timer that would let you if you’ve washed your hands for long enough(20 secs).

This is my work , it’s not the best-looking but it functions! there’s a sensor inside that detects any movement close to the device and then the lights signify how long you’ve been washing your hands, once the light turns green you’ve washed for long enough.

This was really fun to do and I’m happy I was able to get it working. With no real issue.

This was my first attempt at getting an led to blink on a physical circuit and… it did not work :/ I now realize my connections were kind of all over the place.

I did get a blinking led when I tried it directly on the circuit! I should have used a resistor as well, thankfully the led is still in one piece.

Both the switch and PlayStation controllers are equipped with motion sensors when you make certain movements in the consoles respond accordingly. Sometimes (you get attacked for example in-game) the controllers vibrate as a response.
In the kettle, there’s a heat sensor, once the water is done boiling it automatically switches itself off.
In my parents’ car, you can get it to start without actually putting the key in the keyhole? it has a sensor that checks whether the key is in close proximity.
Street lights immediately come on as it starts to get dark and the brightness increases as it gets darker.
In my galaxy buds and sisters headphones, there are sensors that detect touch when you can use certain gestures to get the music to play/ stop or play another song, etc. When a galaxy bud falls out of your ear, or you take one out the music stops playing.
