Particle library for integration with Think Automatic machine learning platform
This library enables Particle.io devices such as the Photon to easily integrate with the Think Automatic machine learning platform. In order to keep this library small, simple and secure it communicates with the platform though a Node.js proxy called ThinkHub running on a machine on the same local network as the Particle device using this library.
Install and run the ThinkHub proxy on any machine on the same LAN as your Particle device. The ThinkHub project can be found here.
The ThinkParticle library is published through the Particle.io library publishing system. Simply search the community libraries for ThinkParticle. The provided example looks like the following and is designed to work with a modified Staples Easy Button although it will also work with any button input.
#include "application.h"
#include "ThinkParticle/ThinkParticle.h"
int led = D7;
int button = D6;
bool buttonPressed = FALSE;
void postCallback(String name, String value)
{
if (name == "LED")
{
if (value == "on")
{
digitalWrite(led, HIGH);
}
if (value == "off")
{
digitalWrite(led, LOW);
}
}
}
// This sets the name of the device, type of device (by guid), and callback for processing
// commands from the platform. To browse existing device types or to create a new one
// go to https://app.thinkautomatic.io/devicetypes
ThinkDevice thinkDevice("Easy Button", "51c68fea-2d6f-46e9-b4d7-0cf772a10920", postCallback);
void defaultCmd(WebServer &server, WebServer::ConnectionType type, char *, bool)
{
/* this line sends the standard "we're all OK" headers back to the
browser */
server.httpSuccess();
/* if we're handling a GET or POST, we can output our data here.
For a HEAD request, we just stop after outputting headers. */
if (type != WebServer::HEAD)
{
/* this defines some HTML text in read-only memory aka PROGMEM.
* This is needed to avoid having the string copied to our limited
* amount of RAM. */

}

pinMode(button, INPUT_PULLUP);

}
