Is there any way to create a sensor that would givea value based on the pattern of on and off. We are putting in a new septic system and it has a pump controller that makes a light on it flash in certain patterns to give information on what the state / error is.
some of the patterns:
constant on = state A
. . . = state B
- - - = state C
.. .. .. = state D
... ... ... = state E
.--. .--. .--. = state F
