Hi! I have an Arduino UNO R3 and I want to get it connected to my laptop, but my friend told me that he does it this way:
Arduino connected to ethernet shield
Ethernet shield to a router (via the LAN port)
Router wirelessly connected to my laptop
The router he uses, takes 9v and is heavier than a dongle.
So, what I want to know is that, whether I can use a USB wifi dongle instead of the bulky router?
If not a USB dongle, than anything that takes less space and less power will do.
