Open a door with a button remotely!
Designed to work with a 12V battery so if the light goes out you can still open the mechanism. It has a 5V power supply and when the button is pressed an NE555 timer sends a signal for 5 seconds to the optocoupler and relay to activate the solenoid and buzzer. In this way the dorr can remain unlocked for 5 seconds and the buzzer will let you know when it is activted.
