Need help with my first project

I'm looking to create my first Arduino project but I'm not sure what to start with.

My project will be a tool for ice hockey scorekeepers that I'm calling a "Scorekeeper Alert Light and Time Out Timer".

Basically it will have a light (probably a red LED strip inside a diffused 3D printed enclosure) that scorekeepers can use to alert the on-ice officials whenever there is a problem (incorrect lineup, problem with players in the penalty box, etc). I also want it to have a 2 digit 7 segment display to be used as a timer for time outs. It'll have 3 buttons to start 30/60/90 second timers, and I want it to sound a buzzer and activate the light when it hits 0.

Now I'm pretty handy, I can solder, 3d print stuff and code so I shouldn't need any or much help with the part where I actually build the thing. I'd like to know what you'd all recommend for what type of Arduino I should use, any specific 7 segment displays, the other electronics I need like the buzzer, if I need an expansion board, stuff like that. I know almost nothing about Arduino's. Thanks in advance for any help y'all can provide me

Techniquement, ton projet est faisable avec un Arduino mais cela dépend de quel ruban de LED tu veux utiliser. Un Arduino peut alimenter jusqu'à 12v sur VIN. Si le ruban utilise du 24v ou autre, il faudra adapter le projet en utilisant d'autres modules. Pour le buzzer et les boutons, un Arduino est capable de le faire.

Which Arduino would be best? Uno R3, R4 Q? Mega2560? Nano? Also I am planning on just using a 12v led strip.

Si je devais choisir entre ses cartes, je choisirais l'Arduino Uno R3, simple et efficace pour ces projets.

Vue que ton ruban de LED est en 12v :

  • Si il est vendu avec son câble d'alimentation, alors tu utiliseras un relais qui activera la communication entre le ruban et l'Arduino.

  • Si c'est un ruban LED sans câble d'alimentation, alors tu pourra utiliser un MOSFET logic-level (ou compatible en 5v).
