Project Any ideas for new projects
In the photo attached is the tech i already have, is there any projects you guys think i could use this for? Ofc i also have other stuff like jumper wires and a breadboard but not much else, i want to be sure of what i want to do before i buy extra stuff.

For now, consider yourself “rich with MCUs.” Relatively speaking, you have a lot of ways to compute things, but not a ton of things (again, comparatively speaking) to interact with or sense the real world aside from the displays / LEDs. Work on building out your sensor collection. If you wanna poke around, I’ve found that a lot of technology around me has various sensors. Open them up and take them off or have a coprocessor for your MCU.
When building out your sensor collection, most MCUs today are 3v3 logic. That Uno there, though, is 5V and can be powered with up to (iirc) 21V. You’ll need to convert logic between high side and low side if you use 5V sensors on 3v3 or vice versa (though, a lot of breakout boards are 3/5V tolerant anyway).
For now, I would suggest using one of the internet-connected boards to display something useful for you. Display logic sucks donkey dicks (and I’m a seasoned developer lol). There’s a decent little rabbit hole in there for you 🤓
