+# LED - RGB Intensity
+
+<!--remove-end-->
+
+
+Demonstrates changing intensity of an RGB LED. Requires RGB LED on pins that support PWM (usually denoted by ~).
+
+
+
+
+
+##### RGB LED. (Arduino UNO)
+
+
+Basic example with RGB LED connected to pins 6, 5, and 3 for red, green, and blue respectively.

+Run with:
+```bash
+node eg/led-rgb-intensity.js
+```
+
+
+```javascript
+var five = require("johnny-five");
+var board = new five.Board();
+
