I have an Arduino Uno and I have a remote sensing project for which I need Wifi connectivity. After doing research, I've found that I have 2 options:
- Buy a WiFi shield for my existing Uno
- Buy an Arduino Yun with built-in WiFi
Looking at costs, I found that a WiFi shield costs more than double what it costs to buy a Yun, so it would seem to me that the best option is the Yun as I'd save some cash and get a more capable board. However, I can't help but think I'm missing something.
What are the advantages of an Uno plus Wifi shield as opposed to a Yun?
