	~~=== '''RGB LED''' ===~~

	~~'''Description'''<br>~~

	~~RGB lights can adjust the intensity of three primary colors (red / blue / green) through the PWM voltage input of the three pins R, G, and B to achieve the full-color mixing effect.~~
	~~In this experiment, we control the RGB lights to display different colors by controlling the PWM values of the three PWM ports. The description of the RGB light interfaces are shown below.~~

	~~'''Description'''<br>~~
	~~I/O port means interface for INPUT and OUTPUT. Up until now, we’ve only used the output function.~~
	In this experiment, we will try to use the input function, which is to read the output value of device. We’ll complete an experiment with use 1 button and 1 LED to give you a better understanding of the I/O function.

	~~'''Description'''<br>~~
	In life, we often see some billboards composed of colorful led lights. Different effects shown on billboard as lights change. In this section, we simulate the effect of advertising lights with LED lights.<br>

	~~'''Equipment'''<br>~~
	* Nano control board*1
	* USB cable*1
	* LED*5
	* 220Ω Resistor*5
	* Breadboard*1
	* Male to female Dupont Lines
	* Male to male Dupont Lines

	~~'''Wiring Diagram'''<br>~~
	~~<br>[[File:055251-6.png\|500px\|frameless\|thumb]]<br>~~

	~~'''Test Code'''<br>~~

	~~<pre>int BASE = 2 ; //the first LED is connected to I/O port~~
	~~int NUM = 5; //the sum of LED~~
	~~void setup()~~
	{
	~~for (int i = BASE; i < BASE + NUM; i ++)~~
	{
	~~pinMode(i, OUTPUT); //set I/O port to output }~~
	}
	~~void loop()~~
	{
	~~for (int i = BASE; i < BASE + NUM; i ++)~~
	{
	~~digitalWrite(i, HIGH); //set I/O into “HIGH”, light is on~~
	~~delay(200); //delay~~
	}
	~~for (int i = BASE; i < BASE + NUM; i ++)~~
	{
	~~digitalWrite(i, LOW); //set I/O to “LOW”", light is off~~
	~~delay(200); //delay~~
	}
	}
	~~</pre>~~


	~~'''Test Result'''<br>~~
	~~After downloading the program, the external small light gradually brightens then darkens, and alternates.<br>~~
