### Configure Wi-Fi SSID and Password in main.h

Source: https://github.com/pubnub/samd21/blob/master/examples/README.md

Before building the project, configure the Wi-Fi network credentials (SSID and password) in the `main.h` file. This allows the Atmel chip to connect to your local Wi-Fi access point. The `TEST_MODE_WITHOUT_PROVISION` macro is also defined here.

```C
#define TEST_MODE_SSID "Enter-your-SSID"
#define TEST_MODE_PASSWORD "Enter-the password-for-the-SSID"
#define TEST_MODE_WITHOUT_PROVISION
```

### Add PubNub Channel and Keys in main.c

Source: https://github.com/pubnub/samd21/blob/master/examples/README.md

In the `main.c` file, you need to specify the PubNub channel name, publish key, and subscribe key. These keys are obtained from your PubNub account and are essential for sending and receiving data streams. Replace the placeholder values with your actual keys and desired channel name.

```C
#define PUBLISH_KEY "YOUR_PUBLISH_KEY"
#define SUBSCRIBE_KEY "YOUR_SUBSCRIBE_KEY"
#define CHANNEL_NAME "YOUR_CHANNEL_NAME"
```
