 This sketch {{ ::example-code-autonomo.ino.zip |}} can be used as an example. The following extract denotes the part corresponding to receiving downlink messages. For example, the received value can be used to trigger some action on the Arduino module.
+==== -. Arduino with Dragino Shield ====
+Devices in the LoRaWAN platform can also be implemented on Arduino boards with Dragino shields. The combined module as well as the basic configuration steps are presented in [[simple_lora_prototype|Simple Prototype of LoRa Communications]]. Similarly to the Autonomo device, you can download the following sketch {{ ::example-code-arduino.ino.zip |}} and modify it according to your preferences. Below you can find an extract of the receiving function for downlink messages.
