Everyone met as a group today. We got a lot done. The UMS now communicates with the circuit, adding users and grabbing users keys to add to the database. Also the circuit is capable of validating users based on the EEPROM (no UMS communication). We have some good ideas to create a very low-power circuit.
Jim did some good work devising a plan to detect the state of the dead-bolt, which is necessary so that we don’t lock an already locked bolt (gear damage). We can’t simply track the state in software because the user can manually override the lock, so this was necessary.
Owen has devised a nice circuit to run the motor both directions powerfully off only 9V. We should be able to very soon integrate all of the systems together into a PCB board and test it on the lock.
Marshall’s menu system is almost done and we’ll be attempting to integrate it on Friday.
