I developed a simple project with the Arduino Yun to automatically post tweets at certain times when the user is sitting on his chair. The idea is to use it to post “bad” tweets about yourself when you are working to much and you don’t want to go running. The comments from your friends should motivate you to move
I developed a simple web app in AngularJS (see the picture below) to send the tweets data from the browser to the Arduino using the JSON format. On the Arduino side I used timers to schedule the posting of the tweets and Temboo to post them on Twitter.
