In the following, we begin our first experiment—blinking LED.
The components used in this experiment are shown below:

This experiment will need a 470ohm resister, one LED, 2 jump wires, and one breadboard.

Arduino Code:

int ledPin=9; //Configure the control digital IO pin
void setup()
{
//set the mode of the digital IO pinto be OUTPUT
pinMode(ledPin,OUTPUT);
}
void loop()
{
//Set ledpin to be HIGH, which is equal to 5V
digitalWrite(ledPin,HIGH);
delay(10); //Set the delay time, 2000 is about 2 seconds
//Set ledpin to be LOW, which is equal to 0V
digitalWrite(ledPin,LOW);
delay(350); //Set the delay time, 2000 is about 2 seconds

The positive pin of the buzzer is wired to digital IO pin 7 of Arduino, and the negative pin is
connected to GND of the Arduino.

Arduino Code:
int buzzer=7;//Configure the control digital IO pin
void setup()
{
pinMode(buzzer,OUTPUT);//Set the mode of the digital IO pin to be
OUTPUT
}
void loop()
{
unsigned char i,j;//Defined a variable
while(1)
{
for(i=0;i<80;i++)//output a sound with a frequency
{
digitalWrite(buzzer,HIGH);//make a sound
delay(1);//delay 1ms
digitalWrite(buzzer,LOW);//silent
delay(1);//delay 1 ms
}
for(i=0;i<100;i++)//Output a sound with another frequency
{
digitalWrite(buzzer,HIGH);//make a sound
delay(2);//delay 2ms
digitalWrite(buzzer,LOW);//silent
delay(2);//delay2ms
}
}
}

Arduino Code:

int key=7;//Configure the button ON/OFF indicator digital IO pin,
which is wired to LED
void setup()

pin to be OUTPUT
}
void loop()
{
int i;//define a variable
while(1)
{
i=analogRead(5);//Read analog input port 5
if(i>1000)//if the value is larger than 1000（i.e., 4.88V）
//set the indicator pin to be HIGH to turn on the LED
