reading frequency, two wire system

Can you measure the coil resistance with an Ohm meter? Might give a hint to a load resistor for testing.

The best thing to do is to write some code on interrupt basis.
For instance DI2 or DI3 on an Arduino Uno.

yeah, as soon as I can, I'm in florida and its pretty much on lock down as far as work goes.

and does anybody have any recommendations on an oscilloscope in the $200 range??

LandonW:
20mph = 1800fpm

1760 as there are 1760 yards/mile and 3 * 20 = 60

40" diameter wheel = 37.68 foot circumference

Not even close - just think about it, the wheel is close to 1m in diameter, so the
circumference has to be around 3m, ie about 10 ft.

it would take the wheel 47.77 turns to make that distance at that speed

47.77 * 60(for poles per turn) = 2866rpm at that speed

yes?

no.

oh hahaha I used the formula for area.. dumb
