Clean Up for Homework

Notes

• This is just some additional instructions needed to try the homework
• millis()
  • Is a command that returns the number of milliseconds that have passed since the board booted.
    • This returns an unsigned long, a 32 bit number.
    • You need to be careful with unsigned long computations to make sure that they stay in that range.
    • The millisecond timer will overflow in about 50 days.
• random()
  • Takes either a max value or a min and max value
  • max and min are longs
  • The function returns a long
  • The RNG can be seeded with randomSeed()
  • This can be initialized with a digital read of an unused analog pin.
• We need a computation for our experiment, so I did a Monte Carlo π computation.
  • Not too difficult to understand
  • Can take as much time as you want
  • Is easy to stick a button press check in the middle.
• Take a look at the simulation
