Background: I'm looking to start on my first real electronics project and I have an Arduino Uno I bought a while back. I've only done a few of the starter Arduino tutorials and that was a while back as well. Starting from very little electronics knowledge, I'm trying to get a bit of advice on how to tackle my first project. TL;DR: I have an Arduino Uno but very little experience with it or electronics.
Project: I want an object that locks, I want the duration of the time it stays locked for to increase by ~1-3% every time it locks. I want to put my nicotine products in there to gradually pull myself off nicotine. I have designed a rough 3D model of the box, which I can 3D print so now I'm looking at the electronics. TL;DR: A box which stays locked for longer, every time it locks.
Electronics: A microcontroller/Arduino/Pi to increase the locking duration; a locking circuit and some form of power supply.
My 2 questions are
Would the Arduino Uno be suited to this type of project?
What sort of components should I be looking for for the locking circuit and power supply (I'm thinking some sort of solenoid actuator and a battery pack)?
