Hi, i want to make a wifi project with my arduino uno, making my home wireless (light bulb, electronics, more) , i saw projects like LIFX which is a wireless led bulb that connect to your wifi in your house.
The problem is... wifi shields are expensive (50$+, and this is too big to enter a light bulb). I am wondering if there is a way to order parts seperately and create your own wifi arduino that connect to your router? Is there a tutorial for that? It will be expensive? It would be great to have small PCBs connecting to the wifi where you can put everywhere in your house for cheap. Thanks!
