If you’re using a brand new SD card, it will probably work out of the box. So before we do anything with the Yun itself, let’s prepare the microSD card. The official getting started guide says, “You’re discouraged from using the Yún’s built-in non-volatile memory, because it has a limited number of writes.” I don’t know what that means, but it sounds bad, so I’m going to take it at face value.
You’re going to need a micro SD card with your Yun. The Yun also has all the pins that you’d expect to see on an Arduino (we’ll cover those in a future tutorial): Since your Yun is set up for the office WiFi, you’ll need to hold down the WiFi reset button for somewhere between 5 and 29 seconds, then go through the steps below to connect to your home WiFi network. If you hold down the Arduino’s WiFi reset button for more than 30 seconds, your Yun will reset to factory conditions! (Though, if you’ve upgraded OpenWRT, the new version will remain.) If you hold the WiFi button for more than 5 seconds but less than 30, it will reset the WiFi networking settings.įor instance, let’s hypothetically say that you’re writing a “Getting Started with the Yun” guide at your office in Chicago, then it snows 19 inches, so you decide to work from home the next day. The Arduino Yun I bought from Adafruit did not come with a microUSB cable. You’ll spend a lot of development cycles with the Yun plugged into your computer, but actually sending data to it over WiFi. Instead, it gets its juice from the micro USB port. Unlike the standard Arduino, the Yun does not have a dedicated port for power. Three buttons: WiFi reset, “Arduino chip” reset, and “Linux chip” reset.Three ports: a standard USB, a micro USB, and an ethernet port.Atheros AR9331 – This is the “Linux and WiFi chip.” It runs OpenWRT, “a Linux distribution for embedded devices.”.When you send a sketch (Arduino code) to the Yun via the Arduino IDE, it’s running on this chip. Atmel ATmega32U4 – this is the “Arduino chip” that controls the pins and lets you do all the hardware hacking that you associate with Arduinos.Check out our IoT Tutorials for Sync for IoT as well.

My guess is that it’ll take you 30-45 minutes to complete this tutorial. run Blink, the “Hello World” of Arduino programs.
#Arduino wifi install#
install the Arudino IDE on your computer.connect your Arduino Yun to the wifi network.
#Arduino wifi upgrade#
upgrade OpenWRT, the version of Linux that runs on the Yun.
