 ==Objective==
-You have learned several LED experiment, then go on studying the RGB LED that is display different color by a RGB LED, including the breathing lamp's effect.
+By now you are familiar with using an LED. Let's take a look at the RGB LED. This new type of LED allows us to display different colors. We can also replicate the breathing light effect from last lesson.
 ==Equipment==

 ===RGB===
-RGB LED contains three LEDs, one is red, the other is green and another it blue.
+RGB LED contains three LEDs: red, green, and blue.
-By controlling three LED's brightness, you can mix up almost any color you want.
+By controlling the three LED's brightness, you can create any color you want.

-Here just list a few kinds of color, you can get color value through other colors modulus software, such as PhotoShop.
+The above program only lists a few colors you can make. You can search online for RGB values for any color you want.
 ==Result==
-In a light can be seen on red, green, blue, yellow, purple, black, white, and effect like a breathing lamp .
+The light will go from red, green, blue, yellow, purple, black, and to white. Then, it will behave like a breathing light as in Lesson 6.
