Here’s my plan: Create a wireless Internet of Things device that records the sounds in my back yard and transfers time-stamped samples to a network attached storage device in my home office for analysis. I shall call this system the “Barkometer”
There are three parts to this plan, the first of which was assembling the hardware. As I’ve been extensively covering the Internet of Things and most particularly Raspberry Pi technology, I had a Raspberry Pi 2 Model B ($35 from Element14) to hand, so that was the obvious choice. Note that because high input data rates are required to handle audio, an RPi 3 Model B might have been a better choice as we will see later.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
