Whenever I add a new programming platform to learn, I'm always looking for ways, beyond its practical use, how it "works" in ways that apply to technology trends. In this case, my project this summer is to learn and develop an Arduino project. And sure enough, MIT, has that answer for me! Take a look at this new programming language they've invented that allows non-technical researchers to create programs that control cell behavior. I'm just now learning about them, both Arduino and this new Verilog driven platform, Cello, but from this article, it looks like both applications rely on programming using "sensors" to control behavior, Arduino = circuit boards and relays, this MIT language, cell compound and energy detection. In Arduino, my humble goal is to turn on my front porch light using my cell phone (starting with MIT AppInventor). MIT's is to cure cancer. It just goes to show, humble beginnings are always worth the effort.
