I want to send data value (temperature, light strength, etc.) to any cloud server to share my data. One best and looking-easiest example is found from here: https://blog.relayr.io/connecting-the-particle-photon-to-the-relayr-cloud/. However, I am stuck in the “Adding your Photon to the relayr cloud and receiving data-publishing credentials (curl)” section because I don’t know where I can ‘open’ the curl.
I would really appreciate if you can provide any simple example to stream my sensor value to any cloud service. I will also appreciate if you can explain how I can ‘open’ the curl and input the command.
