Smart lock using DC motor with encoder

ah thank you so much, quite clever!

missed somehow the rotary_encoder, thanks so much for explaining! does your lock still work nice?

Or were there any further problems then if I may ask?

I don’t use this anymore because it is quite bulky and doesn’t look so nice, but mostly because the motor is using a lot of gears to have more torque which makes it impossible to turn the key from the other side.

I replaced it with this which is using a stepper motor with 3D printed gears and I’ve been using it for about 3 years and it works perfectly.

Either smart lock you use should run without issues for years, but you need to have a good power supply.
