Infrared Object Detector using the Brainstem™ Microcontroller, GP2D02 and DSLCDD2
 
The following example application demonstrates use of the Sharp GP2D02 Infrared Object Detector, DS-LCDD2 IIC LCD and the Brainstem™ microcontroller.
The program uses the newly developed aLCDx.tea library file, which works with the DS-LCDD and DS-LCDD2 range. (The aLCDx.tea can be found here and should be saved in the Brainstem/aSystem file).
The GP2D02 detects any objects in front of it within a range of 10-80cm. This distance is then displayed as a continuously updated number both on the console and LCD screen.
