Hello, I'm trying to make a RFID Tag LOCK and i spotted some problems with my project.
Sorry that i don't have scheme but it works like this (or at least should):
- Reading RFID tag
- Displaying "hacking" msgs
- Giving a signal to relay which supply 12v electromagnet that releses doors
- Reset after 3 min (in code i lowered delay for tests)
Problems i have occured:
The electromagnet probably causes some data change in display (the code works good). I will paste vidios for clearance.
I'm not quite sure how to do a good user friendly lock. I mean that wont stuck if they pull doors. I need your advice :) The electromagnet works fine if nobody pulling the door at releasing time. Thought about servo but it will occur the same problem with pulling at time when relesed.
Im attachating code, videos and pictures:
