My Foginator Updates\/Notebook<\/h1>\n

My project notebook and work can be found below. It includes notes along the way for my personal part of the Foginator and then includes code for the sensor library which I created after testing the sensors functionality.<\/p>\n

Getting \u00a0the sensors working properly was a good start for the project. Test programs for each sensor were built and used to test the functionality of each sensor. The most challenging part was the next portion of the project which was to take the testing code and make one big sensor library where each sensor can be called with one line and output the data needed from each sensor. The code below is the .h header file, the .cpp and the getArduinoData final script for the sensor library. The code below is then used with the Arduino and sent via i2c communication to the Raspberry Pi, which is used to then call these sensors to update a web page created by Chad.<\/p>\n
