Motorized door unlocker!

Hey Ben,

I'm a 15 year old boy who has been watching your videos for a few weeks now and I have always thought it would be awesome to create a door lock that opens by the press of a button, or maybe a remote control, but I'm not 100% sure how to make it or even if it's possible. It would be awesome if you could use this in a future episode!

Thanks

I would suggest, if you want to make it, you check this out:

It is more complex than you are thinking, but would work well if you just took parts out of it and replaced them if you wanted to.

All you really need is an electronic lock, relay, Pi, suitable button, and wires as well as a case and supply for power.

Have the Pi trigger a transistor when the button is pressed. This should trigger the relay connected to the lock which would open or close it.

It would be very easy to do with a Pi, but would be better to use an arduino since it can be left there on and it would automatically go back to the program if anything happened to the power supply, when it comes back on.

Hope this helps!

That's OK.
I would suggest that you don't start fitting it to a door before you have tested it on a fake door just to make sure you don't break an actual door!
