guidance on Mikrobus NFC tag and connecting to arduino
To find an Arduino library for a device, you can search for the term combination

Arduino github &lt;devicename&gt;


because most libraries are hosted on github. The devicename here means the chip on the product, not the product itself. You won't find much for "Mikrobus NFC", but when you search for the chip on it - the  M24SR64 - you can find some promising results.

For example this library, which looks good to me. It was used for this blog article, which is where I found it (though that is a german site. I just wanted to link as reference for the german speakers). It has some examples, that show the usage of the library.



In general: Sometimes there might be no ready to use library for a chip or product to use with Arduino. In that case you need to write that code yourself. Let's take this product as example. It uses the I2C interface and the seller also links to the datasheet of the used chip. In the datasheet you can read, how the chip is used, including the communication protocol, that is imposes on the I2C interface. You could then write the corresponding I2C code using the Wire library.

Fortunate for you there already is a library, so you can first try that.
