Making use of the Raspberry Pi’s GPIO, we hooked up a PIR sensor to trigger a webcam capture event and publish the image to Tumblr.
By far the most challenging part of this project was working with the API. Since it’s a lot easier to find examples of raspi projects written in python than in c++, we decided to use python. For example, the Tumblr API page has example code for python but not c++, adafruit has a great python tutorial for hooking up a PIR sensor to a Pi’s GPIO.
pytumblr is Tumblr’s official API client for python, but the instructions are unclear.
