Hello there. I am absolutely new in these things and i am sorry in advance. So i find this - workshopweekend.net. I need probably the same but i need after the right knock code is "entered" it should be connected with electromagnet lock witch should be open when the code is accepted.
So i have a question - do i need servo? Where should i connect the electromagnet lock and should i change the code?
I want to know it before i buy these things to know will can i do it by my own :)
Thanks in advance, the beer is from me :)
