Choosing the right wearable arduino

Hey Guys,
I am a complete newbie to arduino and would love some guidance with my project...

I would like to get a coin vibration motor to work wirelessly with my arduino so that:
-it vibrates every 5 min time interval, but if a button is pressed (on the arduino which is connected wirelessly to the motor) then it vibrates every 10 min time interval.

-I am going to use 2 NRF24L01 modules
and was looking at this example: https://howtomechatronics.com/tutorials/arduino/arduino-wireless-communication-nrf24l01-tutorial/ <-- **how could i could adapt this for my project and to work with a small portable arduino

(attempting to make it smaller so it fits into a small dome you can clip to your sleeve -like a cufflink)

My main question is: What type of wearable arduino should i use? A lilypad? -if so which version?... a mini/micro would require a breadboard, increasing the size of the project, so i have ruled out this option so far...

Any form of help or direction would be hugely appreciated as this is for a uni project due in a few weeks time :slight_smile:
