 ## Using Capacitive Sensing on the Uno R4
 
 The Uno R4 features a Capacitive Touch Sensing Unit (CTSU) that allows you to use certain pins as capacitive touch inputs. To utilize these capabilities, you can use the [Arduino_CapacitiveTouch library](https://github.com/arduino-libraries/Arduino_CapacitiveTouch).
 
 ### Compatible Pins
 
-For both the Uno R4 WiFi and Minima, the compatible pins for capacitive touch are listed in the [Arduino_CapacitiveTouch library documentation](https://github.com/arduino-libraries/Arduino_CapacitiveTouch?tab=readme-ov-file#compatible-pins).

 ## Conclusion
 
-The built-in capacitive sensing capabilities of the Arduino® Uno R4 provide an excellent way to add touch inputs to your projects. By leveraging the Arduino_CapacitiveTouch library, you can easily integrate touch-sensitive features, enhancing the interactivity and functionality of your designs. Whether you're building a simple touch interface or a more complex interactive system, the Uno R4's capacitive sensing features offer a versatile and user-friendly solution.
-Remember to experiment with threshold values and consider the environment where your project will be used, as factors like humidity and nearby electronics can affect sensitivity. With practice, you'll develop an intuitive understanding of how to tune these sensors for optimal performance in your specific applications.
+Capacitive sensing on the Arduino UNO R4 lets you add intuitive touch controls with minimal hardware, simply pair the board with the `Arduino_CapacitiveTouch` library. Tune the detection threshold for your environment (humidity, nearby electronics, etc.), and you can quickly scale from a single touch button to richer, multi-point interfaces.
