You are so observant. In my effort to understand this module better, I could not find a datasheet, only this
website. It has a -05v- in the part number, so I erased it since it is not what you suggested. What is the bottom right potential for (post #17)?
I have two options, first there is an encoder that comes with the motor so i can keep track of the angle possibly. Knowing this probably wont work due to error in physical systems (gear backlash namely), i was thinking of adding a trip sensor to signal gate open/close status to microcontroller, then shut the motor off using logic ([00] to the 'input' at the module). I'm not sure using limit switches would work since something can block the gate causing the controller to think it was closed.
Just to give you more a little more system info, I eventually plan on using a RF 433Hz Tx/Rx pair to provide the commands to Pi (just ordered them to play with). So I plan on sending a HIGH/LOW to a Rasp Pi GPIO input & the gate latch using a key fob.
I am still curious about the diodes, so whenever you have time (no rush). Thank you!
