BeagleBoards and BeagleBones are inexpensive web servers, Linuxdesktops, and electronics hubs that include all the tools you need tocreate your own projects—whether it's robotics, gaming, drones, orsoftware-defined radio. This webcast will go over some of the recipesin the BeagleBone Cookbook that go beyond BeagleBone Black forconnecting and talking to the physical world with this credit-card-sizedcomputer. In this webcast you will learn:– What is BeagleBone Black? What can you do with BeagleBone Black?– What basic skills will “BeagleBone Cookbook” help me develop?– What are some other BeagleBoards coming out, including SeeedStudioBeagleBone Green, SanCloud BeagleBone Enhanced, BeagleBoard.orgBeagleBone Blue and BeagleBoard.org BeagleBoard-X15– What recipes will work with these other boards and how do I apply them?2

DC voltage causes motorto turn Brush contact resets driveafter partial revolution Drive strength isproportional to inputvoltage There’s a maximum inputvoltage Reversing voltagereverses direction BeagleBone Black doesn’tsupply enough current onits I/O pins50
