Wind Seeded Random Number Generator

True random number generation is hard, but nature can help! This project uses the unpredictability of wind to increase randomness.

How it works: the wind blows and spin the turbine, which spins magnets surrounding a Hall Effect sensor. The sensor's analog reading is then used to seed Arduino's random number generator.

In this project, I demonstrate how it works using an Arduino Leonardo with LCD shield to display both the sensor reading and the generated random numbers.

Hardware:
* Arduino + mounting hardware + LCD shield by DF Robot + 9V battery with connector.
* Hall effect sensor + wire.
* 4 magnets (1/4" diameter cylinder. 1/16" thick).
* 2" T-pins (it's the axle).
* BB gun ammo, stainless steel, 4
