TI 84 with EasyLink

The easiest way to collect data is to use a TI 84 graphing calculator, an EasyLink, and a sensor.  Voila!  You're digital.  The TI 84 has EasyData preloaded.  This app enables the calculator to collect data.  Collecting data is a cinch.  If you connect the EasyLink to a sensor, such as the temperature probe, and connect the EasyLink to the calculator, the TI 84 will identify the sensor and display data on its screen.  Accessing this data is another matter.  The manual has details-too many for a novice.  If you collect data, it's stored in the Stat function.  Watch these!
