A brief overview of a bird feeder that triggers a camera
In this task, we will set up a bird feeder with a motion sensor. Whenever a bird flies into feed on the grains out of the feeder, the motion sensor is triggered to send a message to the Raspberry Pi. A camera module or a USB camera is connected to the Raspberry Pi, which captures some beautiful moments in our backyard.
Srihari Yamanoor (one of the authors of this book) has an extensive backyard where this bird feeder has been installed. Check out this book's website to find out whether we have captured any beautiful moments thus far!
