Rotations Meter
Idea by: The Spunturbo
This rotations meter is made for engine testing.
Connect an input, for example a sensor, that activates every time
engine shaft does ONE full rotation, to the white gate.
Set the LIME timer to time of your choice to measure rotations in it.
Starting from the timer and input gate side 3 rows of grey gates are:
0,1,2,3,4,5,6,7,8,9
Each layer starting from the bottom is:
ones digit, tens digit and hundreds digit
Purple gates are for 7-segment display.
They are already encoded, just a matter
of connecting few wires.
Starting from timer and input gate
gates stand for segments:
top, top left, top right, middle,
bottom left, bottom right, bottom
If not needed, purple gates can be destroyed
UPDATE 1:
Save state has been added.
Highest value from last cycle will be saved
and updated as the time goes.
UPDATE 2:
Fixed counter bug.
Fixed color legend.
Added 7-segment coder.
