// This example uses an Arduino/Genuino Zero together with
|
|
// a WiFi101 Shield or a MKR1000 to connect to shiftr.io.
|
|
//
|
|
// IMPORTANT: This example uses the new WiFi101 library.
|
|
//
|
|
// IMPORTANT: You need to install/update the SSL certificates first:

|
|
// You can check on your device after a successful
|
|
// connection here: https://shiftr.io/try.
