Le programme à mettre dans l'arduino:
---------------------------------------------------------------------------------------
// Sweep
// by BARRAGAN
#include
Servo myservo; // create servo object to control a servo
// a maximum of eight servo objects can be created
int pos = 0; // variable to store the servo position
int analogInput = 3;
int led = 13;
int analogValue = 0;
void setup()
{
myservo.attach(9); // attaches the servo on pin 9 to the servo object
pinMode(led, OUTPUT);
pinMode(analogInput, INPUT);
Serial.begin(9600);
}
void loop()
{
// pour voir si le montage fonctionne
for(pos = 0; pos <>
{ // in steps of 1 degree
myservo.write(pos); // tell servo to go to position in variable 'pos'
delay(15); // waits 15ms for the servo to reach the position
if (pos <>
Serial.println(pos); //variable pos = 0 - 180 ne pas utiliser print mais println
Serial.print("\t");
delay(100);
}
for(pos = 180; pos>=1; pos-=1) // goes from 180 degrees to 0 degrees
{
myservo.write(pos); // tell servo to go to position in variable 'pos'
delay(15); // waits 15ms for the servo to reach the position
if (pos <>
et le programme à mettre dans processing:
--------------------------------------------------------------------------------------
Serial.println(pos); //variable pos = 0 - 180
Serial.print("\t");
delay(100);
}
}
