Building the Solution
The hardware construction for this project closely matches the sensor approach we built for the Tweeting Bird Feeder project. We will once again call upon the Python language to script the server-centric interactions, but this script will also utilize several custom packages to interrogate popular web services offered by US-based courier companies like Federal Express (FedEx) and United Parcel Service (UPS). More specifically, we will:
Attach the force sensitive resistor to an available analog pin on the Arduino and identify a threshold value when weight is applied to the resistor.
Attach the XBee radio to the Arduino and transmit a message to another XBee radio attached to a computer when the threshold value of the ...
