Hi, I wish to apply wifi in my Arduino project but I dunno which component I should add on my project. Few pieces of research on other people project is carried out but still got no idea on it.
Please help to give suggestion. Thank you in advance.
The most common way to add WiFi to an Uno is using an ESP8266. If can solder the headers on it, I would recommend the SparkFun ESP8266 shield.
There are some Chinese ESP8266 shields, but the problem with these is they only have the option of making the connecion to the ESP8266 via pins 0 and 1. That's problematic because the Uno is already using those pins to communicate with your computer. You can work around it, but it's not much fun for a beginner.
