 ### Goals
 
 The goal of this project tutorial is to showcase the capabilities of the Arduino Nano Matter running Tiny Machine Learning models on the edge for gesture recognition. The wand can detect two gestures drawn in the air: **"W" (wing gesture)** and **"O" (ring gesture)**.

+
+### Data Collection
+
+Accelerometer sensor readings are collected at a frequency of **104 Hz**, with a sample duration of approximately **2 seconds**. This results in **200** tuples of accelerometer (aX, aY, aZ) sensor data for each sample (`200 * 1/104 Hz = 1.92s`). Therefore, a total of **600 data points** are collected for each gesture (200 * 3 = 600).

+## Conclusion NEED UPDATE
+
+In this tutorial you learned how to use the Nano Matter Display expansion kit, leveraging all its features like the E-ink screen to display high-contrast graphics with a low power consumption on 2.9" 384x168 resolution. Features like the built-in RGB LED, the 3-axis accelerometer and the temperature and humidity sensor were explained.
+
+Thanks to the E-ink display, your IoT-oriented products can have a better and more natural user experience while maintaining a low power consumption. Allowing you to set up and commission your solution by scanning the QR code and showing real-time sensor data on the screen, being a game-changer feature for your IoT solutions.
+
+### Next Steps
+
+- Extend your knowledge with E-ink displays following the [Pervasive Displays documentation](https://docs.pervasivedisplays.com/).
+- Try all the examples included in the library for a deeper understanding on the API.
+- Start creating your own graphics to display custom data on the screen.
