How to big dome button

Im a student and doing my dt gcse this year, my project requires some user input - a punching bag that has 2 buttons every 90° (except around back) of which the LED lights flash on (one at one time) until you hit the button, basically a batak reaction test (https://shorturl.at/L78bt) but without a counter - although i understand my basic plan and some components, ive never ever operated with microelectronics before and have some questions.

  1. which arduino would work/be most cost effective?
  2. which buttons e.g https://shorturl.at/SZsmW or Huge Big Dome Push Button Range - 100mm Diameter - Proto-PIC
  3. coding element to it?
  4. any good wiring guides or wisdom?
  5. is this reasonable?

    basic cad model*
  1. Nano 3, Pro Mini, Pro Micro
  2. Electrically they are the same. Which can stand up to repeated punching, if either, who knows?
  3. Yes, of course
  4. Draw a schematic and post it here for checking. Hand drawn is fine.
  5. It looks like you could punch it, so yes. You could punch a Volvo. I would call that unreasonable.

cheers, should i schematicise the button seperately (wires just connected to it) or also to the arduino (-pro mini seems like a fair option)

Im complete begginner and would appreciate some how-tos to this

Start with trying to understand and read a schematic:-
Colin's Lab video on reading a schematic

cheers willdo revise resources


smh like this, although pasted 3 times over without extra cells

I would presume you want each button's LED to operate independent of the button-press. So (at a minimum), that would be an Arduino OUTPUT (for each LED) and an Arduino INPUT (to detect each button press).

As far as your schematic, I'm not able to clearly follow.

Also...those buttons don't look very "punchable" (in the sense that I doubt would be able to withstand a few good punches)...

That would be 4 buttons for 180 degrees. You are missing one button.

In post #6, if SW1 is not close, nothing will light... V1 is +, V2 is -.

Where is the Arduino?

Getting some-
Ordered a fitting nano clone (its purple)
And a generic UNO

arriving in 5 days

I only need buttons on the face facing someone...

Thats right... So i would need an arduino to control LEDs as outputs and button keystrokes as inputs.

So i reckon to seperately power the buttons and LEDs, although still connected to the arduino?

That would be 360 degrees.

270°

Thanks for the help everyone

You don't understand your own writing. Your intent is understood... your wording will crash planes.

You show a 180 degree image... (2 buttons / 90 degrees ) * 180 degrees = 4 buttons. Simple math. Hard grammar.

Yea my image is misleading, thanks for pointing it out. Instead I intend it to show 2 buttons per face (from that perspective) instead of the 1 per face thats there.

Just start with building a sketch to blink an independent LED. Then incorporate a button that you can detect it when it’s pressed. master those two activities first. Then you can start playing with a button that has a built in LED

smh like this maybe then


however is it possible to simplify this schematic?
