Beaglebone Black is the most recent incarnation of the Beaglebone open source hardware platform. For less than $50, the board includes Ethernet, graphics processing, 4Gb of nonvolatile storage, and ports supporting USB, HDMI, and Beaglebone's custom I/O add-ons, called "capes". Here's how to run some simple commands to toggle digital I/O on the board!

We've all been there - you've spent hours and hours trying to get that sketch working, but somehow, you're not reacting well to time critical events in your system. Maybe it's a wireless peripheral indicating when a packet is ready. Maybe it's an external Flash device signaling when data is ready to be read out. Maybe it's as simple as a button push that you need to react quickly to! But, try as you might, it seems the best way to see these sort of events is to just digitalRead() that pin over and over in your main loop() function until something interesting happens. ...or is it?
