We recently remodelled our kitchen and dining area, and I wanted some art piece on the wall but couldn’t decide what. For months the wall was a little bare and we were having a lot of dinner guests. I realised our WiFi password was too complicated to keep reading out to family and friends so I built a QR code in Lego that automatically connects you to our guest WiFi. It looks good, and it’s Lego so it was a fun project with the kids. It took about 4 hours to build. The only problem was having enough 1x1 tiles to put on a 37x37 matrix.
Today I learned you can generate a QR that connects to WiFi.

Android has this feature for a long time. Share the QR code even with iPhone users. And it will add them to the wifi
The best part is that you can generate the QR code from your phone. It's a button in the wifi settings. Really easy way to share it from one phone to another.

You can also read the QR code from your Linux laptop.
Install zbar-tools and use zbarcam from the command line. It will read the QR code using the webcam, and now you have the Wi-Fi credentials.
Or any other data in the QR code.
Thanks for sharing this, sounds like a cool activity to do with kids (and I didn't expect to find one on this thread!), will definitely steal that.
Does this work for iOS yet? Last time I was trying out wifi qr codes only android handled them correctly.
Yes, it works for both Android and iOS.
Sweet! Now to make some qr art. My last iteration was an NFC sticker behind a painting but people have a hard time with that one.
I solved that problem with an NFC sticker in the hallway. Anybody with a recent (2-3yo) phone can just tap the sticker and get online.
