Duinotech XC4392 LoRa gateway
Private LoRa protocol example :
Support Devices: LG01 Single Channel LoRa Gateway
This sketch is running in LG01. LG01 with firmware version v4.3.3 or above
Example sketch shows how to get sensor data from remote LoRa Sensor and Store the data into LG01.
The LG01 has daemon script to check the data periodically and update the data to IoT server.
The LoRa Protocol use here is private LoRa protocol which base on RadioHead Library.

Arduino sketch for controlling music amp power (via relay) from audio signal
* 2020 Jon Robinson
* MIT License
* Arduino sketch which using envelope/peak detector circuit output signal to detect if music playing.
* Opens/ closes a relay accordingly - relay intended to switch amp on and off.
// Two analog pins connected to envelope detector circuits
// one for left channel, one for right channel
