1. Introduction
LED lamps are also known as light-emitting diodes, made of mixed compounds, namely gallium (Ga), arsenic (AS), and phosphorus (P).Gallium phosphide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light.The reverse breakdown voltage of the LED is 5V.The positive伏安特性曲线too steep，must be connected in series with a limiting resistor，in order to control the current flowing through the pipeline when in use.

void setup () {
pinMode (ledPin, OUTPUT ); //设置数字9口模式，OUTPUT：输出模式
}
void loop () {
digitalWrite (ledPin, HIGH); //HIGH设置为5V左右 PIN9
delay(1000);；//设置延迟时间，1000 = 1S
digitalWrite (ledPin, LOW ); //LOW设置为5V左右 PIN9
delay(1000); //设置延迟时间，1000 = 1S
