Can anyone help me decide which components are best for my product?

hello, I am working on a project for my year 12 major work. my design proposal is a mechanical child proof lock for cabinets, cupboards and pantries. i want to use theses components: a solenoid lock, a fingerprint module, and an Arduino board. i am not sure which type is appropriate for this application. if anyone could suggest which type to use i would greatly appreciate it

Hi Samantha,

Cool project! I would start with these parts:

You will also need something to control the Solenoid with, like a MOSFET, and a power supply to drive it all!

thank you for the response, I will look into these options.
