[time-nuts] Generation of pulse train with 1/4 noise

[Bob Camp]

Hi

Ok, how about a nice simple table? Something in the  500  to  4K entries shouldn't  repeat often enough to be noticeable. Each entry probably can be a byte.

The Arduino just uses timers to open and close solenoid valves to create the right frequency and amplitude of motion. Right now it has a somewhat unrealistically uniform pulse rate.
