Per http://www.linuxjournal.com/content/may-2014-issue-linux-journal-cool-projects:
In true "Cool Projects" fashion, Joshua Datko combines two awesome
bits of technology into a teeny, tiny, super-powerful device. He
combines the surprisingly powerful BeagleBone Black with an ATmega328p
microprocessor. The BBB plus Arduino? It sounds like a nerdy version
of, "hey, you got peanut butter in my chocolate"—it's a marriage made
in heaven.
Congrats Joshua!
