You have included the ThingSpeak library but you arent using it. We really reccomend using the examples in the ThingSpeak library. They take care of many issues you will have. YOu can see them in the github repo or if you are using the Arduino IDE, in the File > examples > ThingSpeak menu.

In the above code, you have some extra '<' and '>' characters, but I really reccomend getting rid of this code and starting with theThingSpeak library examples.

Great, thanks for switching the example. That one is an ok example, but I actually meant something like one of these examples.

It looks like in your code, you aren't calling the writeTSData() function. I wouldn't expect there to be any write to thingSpeak using the code you provided. I suggest you start with the example and then work in the details of your specific case.

What are you seeing on the serial monitor?
