Magic 8 Ball v2 with I2C LCD

Turn it into a real Magic 8 Ball

Once the circuit works on your breadboard, you can fit it inside a 3D printed Magic 8 Ball, designed by my friend Ben Eadie. The print files are free on MakerWorld, and the finished sketches for both the regular and the I2C LCD are on GitHub.
