Does this work as a system?


I've tried to create a flow diagram of some electronics I'm trying to do for a project at home. The photographs of the modules are just to clarify what each coloured box contains. The idea is that it will be a motion sensor for a picture frame so that when someone walks past it will turn on some led lights for a set amount of time. The lights are also controllable in terms of colour/mode. (The USB doctor is just to trick the battery into not going into auto-shutdown)

I tried to make a circuit diagram but I couldn't figure out how to create modules - so I've added a link to the PDF with the block diagram in:!AqVAzJx72nN4huIDBvpM8HZPl1ZedQ?e=d2rGFe

I just want to know if it will work? Thank you in advance for any help

Well, I would suggest to start as simple as you can and later on, add sub-groups.

There are many circuits available on the web based around a motion sensor (PIR motion sensor), and one of the most versatile and easy to transform and expand are built around MCU-like entities. As example, based on the Raspberry Pi Pico, with the "standard" beginner kit, there is a simple project in this (free) book from site. You will need the Pi Pico and the starting kit such as this one in that specific case. Other circuits built around other MCU are also available on the web.
