So I've been browsing around for a whole looking for a good microcontroller that's super small. So far the smallest one I found was an Arduino Nano. But before I go buying it, there are some questions I have about it.
- Is Bluetooth compatible with it and if so where would I get the Bluetooth code?
- Is there anything smaller than it that's Bluetooth compatible?
- Would an Arduino Nano (Or the device in the question above) be able to play sounds?
