In the previous hardware post, I wrote about a few different directions we could go to integrate sensors with a mobile app. The simplest way, however, is to re-program a button on an existing bluetooth headset or wired earbuds. To start, we can write a basic mobile app that will do ‘what we say’ when the button is pressed. For example, with the ‘pin’ feature, when the button is pressed the app will record the longitude, latitude and/or time.
I found these wireless headphones the other day. While Apple’s wired earbuds will work just as well for initial experimenting, these could be a great wireless option. They both stream music and handle phone calls, as well as have the button input.
