I'm a beginner on Arduino and Adafruit IO.
I'm trying to send data to my feed with a W600 Grove connected to my Arduino Uno.
The serial monitor shows I'm connected to wifi and data is send, but nothing comes up on my feed. I checked the key and feed name several times.
I use the following code, an example from the GITHUB. Can anyone tell me whats's wrong? Is it in the wifi.httpPost part?
