// arduino-tx
//
// Sample sketch for transmitting data using "ggwave"
//
// Tested with:
// - Arduino Uno R3
// - Arduino Nano RP2040 Connect
// - NodeMCU-ESP32-S
//
// If you want to perform a quick test, you can use the free "Waver" application:
// - Web: https://waver.ggerganov.com
// - Android: https://play.google.com/store/apps/details?id=com.ggerganov.Waver
// - iOS: https://apps.apple.com/us/app/waver-data-over-sound/id1543607865
//
// Make sure to enable the "Fixed-length" option in "Waver"'s settings and set the number of
// bytes to be equal to "payloadLength" used in the sketch.
//
// Demo: https://youtu.be/qbzKo3zbQcI
