I have just finished running an iOS course in beautiful Copenhagen. It was a week of great fun (and laughter!) and what's more impressive than using the app developed by the participants to take a group selfie! Andreas Kleist Svendsen (on the right of this photo), created this app.
The above photo was taken with an app connected to a Ti SensorTag through Bluetooth Low Energy. When a button on the SensorTag is pressed, the app automatically takes a picture with the front camera of the iPhone. How cool is that!
(This class is super smart. Throw them a challenge and the solution pops up in 10 minutes!)
