For my first Yún project, I wanted to focus on the Atheros processor because the Atmel processor is identical to that of the Arduino Leonardo and functions essentially the same. But what to do? As it turns out, we have a hot box that we use to keep the radios dry for our JeeLabs products, and when it was first set up we added a humidity sensorconnected to a JeeNode USB that output humidity and temperature data to a LCD screen via an LCD plug (for the sake of product placement, I might as well mention that a Jee ProtoBoard was involved as well). The thing is, every now and then the darn thing would freeze and need to be reset, and with everything that goes on here no one really has time to check on the hot box with any kind of regularity. Clearly we needed a way to be able to check the status of the hot box from anywhere. That’s where the Arduino Yún would come in.
