    <p>I'm trying to send a JSON string via PUT from an arduino in order to control a philips Hue smart light. I've googled and found a lot about POST and GET, but not much on PUT. I'm attempting to PUT "{"on":false}" to my local Hue bridge (/api/[key]/lights/3/state), but don't now how to format it. Can anyone help? </p> <p>Here's the console info when I successfully send a request using the Hue's debugging tool: </p> <pre><code>Accept text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Encoding gzip, deflate Accept-Language en-us,en;q=0.5 Connection keep-alive Content-Length 12 Content-Type text/plain; charset=UTF-8 Host 192.168.1.8 Referer http://192.168.1.8/debug/clip.html User-Agent Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:12.0) Gecko/20100101 Firefox/12.0 </code></pre> <p>Here's what I been trying, unsuccessfully:</p> <pre><code> #include &lt;SPI.h&gt; #include &lt;Ethernet.h&gt; byte mac[] = { 0x90, 0xA2, 0xDA, 0x0D, 0x83, 0x9D }; byte ip[] = { 192, 168, 1, 199 }; byte gateway[] = { 192, 168, 1, 1 }; byte subnet[] = { 255, 255, 255, 0 }; void setup() { Ethernet.begin(mac, ip); Serial.begin(9600); delay(1000); } void loop() { EthernetClient client; IPAddress server(192,168,1,8); if (client.connect(server,80)) { client.println("PUT /api/[key]/lights/3/state HTTP/1.1"); client.println("Connection: keep-alive"); client.println("Content-Type: text/plain; charset=UTF-8"); client.println("Content-Length: 12"); client.println("\"on\":false"); } else { Serial.println("Connection Failed."); Serial.println(); } delay(5000); } </code></pre> <p>I've also tried it with:</p> <pre><code> "Content-Type: application/x-www-form-urlencoded" </code></pre> <p>rather than UTF-8. </p> <p>According to the API, turning a light on/off is supposed to just be a matter of sending a PUT request with {"on":true/false} to the Hue bridge.</p>

    2. COI know that it is successful in sending it to the Hue bridge address. Unfortunately, I don't know how to read and parse the response JSON on an arduino. According to the API, turning a light on/off is supposed to just be a matter of sending a PUT request with {"on":true/false} to the Hue bridge.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
