-Capacitive sensing is a technology that detects changes in capacitance to determine the presence or absence of a conductive object, such as a human finger. This principle is widely used in touch-sensitive devices. The Arduino® UNO R4, both the [WiFi®](https://store.arduino.cc/products/arduino-uno-r4-wifi) and [Minima](https://store.arduino.cc/products/arduino-uno-r4-minima) versions, come equipped with built-in capacitive sensing capabilities, making it easier to integrate touch inputs into your projects.

 ## Conclusion
 
-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 (such as humidity and nearby electronics), and you can quickly scale from a single-touch button to richer, multi-point interfaces.
