Project in question: http://www.instructables.com/id/Arduino-Weather-Station-AWS/
Note: Did not include the Soil Humidity sensor in my project, but however still followed through with the given steps on connecting all other parts to the Arduino
Following the wiring/assembly steps on this project, I have run into difficulties in actually getting the code to run onto my Arduino. However, instead of following the given wiring diagram image, I simply followed the wiring connections between the components and the Arduino pins that were written on the project website (Which might be a part of my issue)
I then downloaded the given library file, in .rar, decompressed it, and then moved it to the Arduino "libraries" folder, per instructions on how to manually install a library for Mac (at Installing an Arduino Library - SparkFun Learn). I then downloaded the code for the weather station, and opened it in the Arduino IDE. Finally, after attaching the library given for the project onto the sketch, I received multiple errors preventing me from uploading the sketch to my Arduino.
Also Note: I am inexperienced in Arduino coding/programming, and might have thus overlooked a simple error in my wiring, in editing the code, or in installing the library. Please correct any mistakes I might have, and probably have, made.
