What Does It Do?
WebJack is a wired, bidirectional data link between the Arduino Uno and your phone, established via headphone jack. It uses two distinct frequencies for a modem-like serial transmission of data. WebJacks runs in the browser and its goal is to provide a way to read sensors without the burden to install native applications. Look for recent updates on Public Lab here.
This is a list of community-generated guides for specific applications and the development of WebJack. These activities can be categorized, and some may be more reproduced -- or reproducible -- than others. Try them out to build your skills, and help improve them by leaving comments. Together, we can repeat and refine the activities into experiments.
