Background. I was asked to put together a 2 day class on the internet of things at PNCA so I suggested that we try out the Adafruit huzzah.  while I was looking for it I came across the Sparkfun Esp8266 “thing” and the Esp8266 dev board. I used the Sparkfun Esp8266 dev board to implement a… Read more »

To do this, it sends a pulse to the sensor to initiate a reading, then listens for a pulse to return. The length of the returning pulse is proportional to the distance of the object… Read more »

It would be great if we could have a little group show at PNCA. I could bring this piece and the last class project.
