Noiseometer Adafruit.io test code

noiseometer_test.ino

// This example uses an Arduino/Genuino Zero together with
// a WiFi101 Shield or a MKR1000 to connect to shiftr.io.
//
// IMPORTANT: This example uses the new WiFi101 library.
//
// You can check on your device after a successful
// connection here: https://shiftr.io/try.
