Arduino client is a library that allows connecting your IoT devices to the thinger.io cloud platform, or even your private server deployment. This is a library specifically designed for the Arduino IDE, so you can easily connect your devices.
It supports multiple network interfaces like Ethernet, Wifi, and GSM. It requires the latest Arduino version (at least 1.6.3).
You can easily install the libraries with the Arduino Library Manager searching for `thinger.io. If you need more help, please read the topic posted in our community forum.
In the thinger.io platform, each device or thing can define several resources. A resource is like a function that can be executed remotely in your device in real time. This way you can actuate over your devices like turning on/off lights, or extracting information like reading a sensor value. You can take a look to the examples provided in the library to start setting your own resources. You can define several resources in the setup() method.
There are three different types of resources:
Input
Using the operator << pointing to the resource name represents input. In this case this function takes one parameter of type pson that is a variable type that can contain booleans, numbers, floats, strings, or even structured information like in a json document. The following example function will receive a boolean that will allow turning on and off the led.
thing["led"] << [](pson& in){
digitalWrite(BUILTIN_LED, in ? HIGH : LOW);
};
Output
Using the operator >> pointing out of the resource name means output. As the input function, it contains one pson parameter, that will allow storing our output information. In this case each time the function is called it is filled with the millis() value (the time the device has been running), but you can put here your sensors readings.
thing["millis"] >> [](pson& out){
out = millis();
};
Input/Output
Here it is used the operator = for defining a function that have both input and output. In this case the function takes to different pson parameters. One for input data and another one for output data. The following example will output the sum and multiplication of two different values (value1, and value2) provided as input. Notice here how the pson structure can store values with keys, like any json document. The result provides two different values in sum and mult keys, that it is translated to json when you access them from the API.
thing["in_out"] = [](pson& in, pson& out){
out["sum"] = (long)in["value1"] + (long)in["value2"];
out["mult"] = (long)in["value1"] * (long)in["value2"];
};
This library is currently being developed and should not be integrated in any production device until it is more mature and tested. The library interface may change as it evolve to a stable version. Some things that requires attention now are:
- Document code
- Provide more examples and use cases
- Test with different devices that support the Arduino IDE (Tested on CC3200 with Energia).
- Improve the reconnection mechanism for some interfaces.
