==Objective=
This lesson will teach you to derive servo by Microduino without library.

==Equipment==
*'''[[Microduino-Core]]'''
*'''[[Microduino-FT232R]]'''
*Other equipments:
**Breadboard Jumper one box
**Breadboard one piece
**USB Data cable one
**Servo one

==Schematic==
[[File:第七课-Microduino控制舵机原理图.jpg|600px|center|thumb]]

==Program==
<source lang="cpp">

int sp1=7;//Define the servo port pin
int pulsewidth;//Define the pulse width
int val;
int val1;
int myangle1;

//servopulse function
void servopulse(int sp1,int val1)//Define a pulse function
{
myangle1=map(val1,0,180,500,2480);
digitalWrite(sp1,HIGH);//Set the servo port to high
delayMicroseconds(myangle1);//Delay time
digitalWrite(sp1,LOW);//Set the servo port to low
delay(20-val1/1000);
}

void setup()
{
pinMode(sp1,OUTPUT);//Set the servo port as output
//Set the baud rate
Serial.begin(9600);
delay(500);
Serial.println("servu=o_seral_simple ready" ) ;
}

void loop()//Map the number 0 to 9 as the Angle of 0 to 180, and let LED flashing the corresponding number
{
val=Serial.read();//Read the serial port value

if(val>'0'&&val<='9')
{
val1=val-'0';//Get the pure number
val1=map(val1,0,9,0,180);//Convert angle to pulse width value of 500-2480
Serial.print("moving servo to ");
Serial.print(val1,DEC);
Serial.println();
for(int i=0;i<=50;i++)//Given enough time to make servo to rotate specified angle
{
servopulse(sp1,val1);//Invoke the pulse function
}
}

}

</source>

==Debug==
Setp 1：Setup circuit, as following:

[[File:第七课-控制舵机电路.jpg|600px|center|thumb]]
Setp 2: Copy the code to IDE and then compile, run it.

Setp 3：Open the serial monitor, input 1 ~ 9.
[[File:第七课-串口监视器输入0到9.jpg|600px|center|thumb]]

==Result==
Enter a number, the servo will rotate corresponding angle.
