Hello everyone good morning?
Guys I've got a question regarding sending an electrical pulse to unlock an electronic turnstile. I already have the design ready, just missing making this wrist that do not know how you do. All examples that more research is speaking as opening and closing the serial port, if anyone knows how to make or only some example to send this pulse, thanks.
Thanks for the help. I already have a ratchet that uses 2 serial port, Serial RS232 5 volts. I found some stuff that uses DLL, but this model does not need to ratchet DLL according to the manufacturer, he just advised me to send 5 volts to this door that unlocks (thus giving a spin), I just want to 5 volts for programming unlock the turnstile.
[update from OP's answer]
Personally, I would like to know how do I capture the turning of my ratchet to make the turn? I found this example on the internet and found very explanatory to learn to work with serial ports.
Just want to know how to lock the turnstile when you pass?
Someone who works with automation systems could explain to me how to do to capture the spin ratchet to lock automatically?
