Idea
For this project, my initial idea was to use a simple interaction as a switch to light up the LED light. I think hugs is the most suitable, because hugs usually gives us warmth and energy, which can symbolically ‘light up’ a light.
Implementation
I create a simple circuit like in this one:
I connect the 3.3V to the resistor -> LED -> ground. However, from the 3.3V to the bread board, instead of connecting the wire directly to the resistor, I attach it with a piece of tin foil to my plushy. I also attach another tin foil on my T-shirt, this tin foil is attached to a wire, which is connected to the resistor. Hence, when I hug the plushy, the tin foils touch, completing the circuit and turn on the light.

My project implementation was fairly simple, so I did not encounter many problems. Nevertheless, I do have some tips from my first experience working with Arduino. Initially, I tried connecting the wires with regular tape, which didn’t work at all since it isn’t conductive. I then switched to tin foil and wrapped it around the connecting points. Next time, I would use conductive tape or male-to-female wires instead.
Reflection
I enjoyed creating this project. I think the components provided in the Arduino kit make building physical projects much easier. I also try to look at “switch” in a different perspective to come up with a switch which is not only unusual but also has some kinds of meaning.
