This project uses a Raspberry Pi 3 computer to monitor the volume of sound in your home (via the Cloud) to see if and when your pet is upset.
The best part: if your pet gets too anxious and starts barking or making other loud noises, soothe their sad lil’ soul by turning on music or your own (pre-recorded) voice!
Along with the Pi (and speakers), we’ll use the SparkFun MEMS microphone breakout board to measure volume levels and trigger the audio player. Data is uploaded to the CloudMQTT service using the MQTT communication protocol.
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.
