ICStation sent us a BMP-085 Barometric Pressure Sensor. This sensor is 5v friendly, and works with the common BMP-085 libraries that are available. We are using the same library and example code we used with the Adafruit BMP-180. See the

ICStation sent us a 8 Character, 7 Segment Display driven by a MAX7219. There’s no documentation for this display, but a bit of googling found a library and a sample sketch that activated 4 of the 8 characters. The module

Ok, that was a long title, but what does it mean? I have a ham radio buddy that wants to control a variable capacitor with his Arduino. I’m using a Rotary Encoder (digital) for precision instead of a potentiometer (analog)

I have added a Barometric Pressure Sensor to our Web Based Weather Station, and added calculations for Heat Index and Dew Point. You can read about how to build the Weather Server at http://www.instructables.com/id/The-Super-Simple-Arduino-Weather-Web-Server/ and I will be adding the new features

Several of my projects use Ethernet to communicate data back to a server or internet connection. Our Web Enabled Weather Server for one. I’ve decided to power the remote arduino and sensor board over the ethernet connection. Common Power Over

Adafruit makes a nice barometric pressure sensor (BMP180), but their tutorial is designed for the BMP085 and does not compile on Arduino 1.05 It has a built in temperature sensor, and we calculate our current altitude, which is not exact,
