-### What are Multi-Digital Pins?
+### What is PWM?
 
-Some modules use **more than one digital pin** to work properly. These pins allow the module to send or receive multiple signals at the same time—for example, controlling multiple LEDs, handling different colors, or measuring distance with precise timing.
+PWM (Pulse Width Modulation) is a technique used to **control power** to devices by turning the signal on and off very quickly.  
+By adjusting how long the signal stays on during each cycle, we can control things like **brightness**, **speed**, or **intensity**.
