Apologies if this topic irks anyone.
I’m trying to detect when someone churn a butter churn, but I won’t be able to attach a rotary encoder to the axle that it turns on. Does anyone have any ideas on how this could be done?
Maybe I should be using a gyro instead?
I tried using a tilt switch; if the switch has been turned on 20 times in the last second, then some one has been churning it, etc.
Any ideas? All help appreciated.
