Hello everybody, let me know if this is a dumb question and this isn't the right spot to post it, but I'm trying to make a door lock that can detect 3 separate fingerprints and a code on a keypad. (which would be displayed on a lcd display) after that i would like to make it control this latch motor and i was told to use a tip 122 transistor, so ill use that too.. are there any parts im missing? or will that do it (oh yeah i forgot i would like this to run on a esp32 development board, or anything that is small and permanent)
You tell us. It's preferred format if you post a drawing of your proposed project, hand drawn is fine, rectangles and lines are fine, as a schematic/circuit illustration as you imagine it, or better yet, as you've been working with.
Also, using the code tags, post your sketch and tell us what is and what isn't working for you.
That seems to be the way to attract the most assistance.
There are a lot of tutorials on line that will show you that. Also there is a book called the Arduino Cookbook, it is a great companion for somebody starting with Arduino and even those more advanced.
If this is going to be a serious hobby/endeavor I highly recommend you learn the language of electronics, Schematics. KiCad is a full blown package without any limits and it is free.
