 Now, it is time to test our entire data logging application. We will use an [MKR WiFi 1010](https://store.arduino.cc/products/arduino-mkr-wifi-1010); this board will periodically send the value of a counter to the Grafana dashboard via the local MQTT broker deployed in the X8.
 
-First, let's ensure we have the require core for the MKR WiFi 1010 installed, the **Arduino SAMD boards (32-bits ARM Cortex M0+)**. Please, refer to [this guide](https://docs.arduino.cc/learn/starting-guide/cores) if you are not familiar with the installation of additional cores in the Arduino IDE. We also need to install the libraries we will use to send data from the MKR WiFi 1010 board to the data logging application via MQTT. Go to **Tools > Manage libraries...**, search for **ArduinoMqttClient** and **WiFiNINA** and install the latest available version of both libraries.

 Now, let's open a new sketch and create a new header file called `arduino_secrets.h` in a separate tab; to create a separate tab in the Arduino IDE, click the arrow symbol underneath the Serial Monitor symbol, then click on the "New tab" option. In this header file, we are going to store our Wi-Fi credentials:
