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!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
