|
*
|
|
* This example shows how to use the connectors on the shield
|
|
* to interact with the LoRaWan network.
|
|
* Connect a tinkerkit button to IN2, a tinkerkit LDR sensor
|
|
* to IN3, a tinkerkit buzzer to OUT5 and a tinkerkit led to
|
|
* OUT6.
|
|
* Every time the button is pressed a packet cointaining the
|
|
* value read from the LDR sensor and a count of the number
|
|
* of button pressure will be sent (note that the packet is
|
|
* sent in the Cayenne format). If the node receive a packet
|
|
* with value 'a' the buzzer will sound. Any other received
|
|
* packet will change the led's status.
|
|
|
|
* Change the keys below to fit the application in your server.
|
|
*
|
|
* Note : If you're using this example with an Arduino Primo download
|
|
* the ArduinoLowPower library from the library manager.
|
|
*
|
|
* This example code is in the public domain.
