I want to trigger a laser externally and I want to trigger it when a rotating small wind turbine blade passes a specific angle. I have a digital signal which tells me when the blade passes that angle. The blade rotates at 13 Hz, but I want to trigger the laser at 1 Hz.
So I need a tick counter that can count the picks in the digital signal and ignore 12 of them, but passes the 13th one. I am looking for a stand alone sensor that can do it for me. That would be great if I can adjust those frequencies too. Any suggestions would be appreciated.
