Open doors from any connected device thanks to your Raspberry Pi


Since the arrival on the market of Raspberry Pi Many have been the developers who have seen how, thanks to a small very cheap card to acquire, a world of immense possibilities and opportunities was opened for everyone who knew how to see them since it was not necessary to be a large engineering study or have high knowledge in the world of programming and electronics to make any project work.

This time I want to show you a rather unique development, basically we are facing a system open doors connected to the internet that would allow any door to be opened as long as this peculiar lock controlled by a Raspberry Pi is properly installed on the door we want to control. As a detail, tell you that this project has been carried out by the Western Michigan University Computer Club who have decided to fully automate the room in which they work so that anyone with a series of privileges, basically who is inside the club, can enter their room without the need for keys, just with a connected device.

In order to bring this peculiar door opener to fruition, the team got down to work and created a series of gears connected to a very basic motor and a 5v relay that is used to maintain power when the device is not in use. All this connected to a Raspberry Pi that is the true one in charge of synchronizing all the movement and giving power to the motor after checking through a series of sensors previously if the door, at the moment the signal arrives, is already open or not.

If you are interested in seeing how the project works and even in recreating it, tell you that in this link you have all the necessary information and even a list with all the parts used.
