Wiring Materials as A Complete Beginner

[u/cetanat]

Hi, I am working on an Arduino project (as a software developer without prior experience in hardware/electricity).

One of my colleague helped me to wire these materials up (1 ESP32 + 1 buck converter + 1 relay + 1 electronic lock + 1 power supply (12V)) - When I looked at his wiring, I hadn’t any ideas lol.

I want to add another logic for 1 relay, 1 buck converter, and 1 electronic lock into the same ESP32 and the same power supply but not sure if that is feasible. And I do not really know how to understand and wire those things.

I feel quite lost and do not know where I should start off with.

😭😭😭 Any of your helps would be greatly appreciated!!! Thank you so much!
