Mr Noisy Hot Potato

This build is quite easy to test with a moderate amount of parts

The main aim is to recreate the game "hot potato", where u have to keep the ball moving by throwing it to the fellow participants first one who drops it or make the ball scream for 5 notes u lose.

This idea also allows for expansion with more lights and such.

Resistors that go with the LEDs of your own choosing mine where simple red, yellow and gree

I laser printed a box for inside a basketball I had laying around but u can make of your own casing.

and a power bank that u don't mind using or losing.

after making a Prototype with a small speaker, me and my friend made the code for the interface between sensors. The code is included in this step (its the sketch or in plain text)

drew the schematics for what I had to solder and proceeded soldered most of the things u need to know are in the photos.

Also, my way of soldering was not the most space-efficient so try to put the pins on the other side.

Honestly, u can make the case out of anything as long as u have a box to put the Arduino in and a sphere to put the box in and you are set.

u will need a cube of around 10~12 cm on all sides depending on how well u managed to solder it.

Test it before u put Spray foam in to fill in the gaps.

if everything went well (praise murphy) u should be ready to start this throwing this Foamball that could look like a potato at your friends or innocent bystanders (don't) forcing them to participate in your game of hot potato.
