I'm trying to make a piece of code

[Alislugacool]

I'm a new coder trying to make an app which helps my friends we would like the app to count every time we do an attraction at a theme park by pressing a button and displaying that to a Bluetooth light up display can anyone help me as I don't know if this is even possible thank you in advance

You need to break this down, it's a lot for a new coder...

Start with making a simple app (for what? Android, iOS, etc), which needs a list of ride buttons...

LOL, then do some bluetooth examples to keep your friends notified!

Maybe a good idea is: buy a raspberry pi?

It is cheap, < $200 I believe and has a programmable interface so you can connect LEDs and make them light up and other things. Early stage robotics!

I believe raspberry pi is at version 5 now. I never owned one, so I can't say more about them.

I'm sure there is lots of good advice on the internet about how to use a raspberry pi.

A simple application like this could be done with a small microprocessor.
Something like this.

And you can use Micropython with different dev boards. The most used for IoT projects is the ESP32. If you require a smaller dev-board, I would suggest this one: https://www.seeedstudio.com/Seeed-Studio...-6471.html

But before you start, you should learn about the protocols used in microelectronics.
Often you require SPI or I2C for Displays, Sensors etc.
Then you need to pay attention on Logic Levels. All those microcontrollers are working with 3.3V. If you apply more, then it kills the microcontroller.

Then an additional layer comes. Bluetooth is a monster. If you're using Micropython, then Bluetooth Classic isn't supported. The controller is capable of it, but it's too much to include it in the Micropython firmware. But Bluetooth LE is supported via Micropython:

• https://docs.micropython.org/en/latest/l...tooth.html
  
• https://github.com/micropython/micropyth...oth/aioble
  

Edit: There is also Circuit Python, which is a fork of Micropython: https://circuitpython.org/

Tools you can explore

• Flutter + flutter_blue library → for Bluetooth.
  
• React Native + react-native-ble-plx → for BLE.
  
• Arduino IDE → to program microcontrollers.
  
• MIT App Inventor → easy drag-and-drop app builder with Bluetooth support.
