salut tout le monde alors je suis nouveau dans le monde de l'arduino
j'ai effectuer un code qui fait changer de couleur une led RGB
//i/o pin declarations
int rpin = 9;
int gpin = 11;
int bpin = 10;
//function prototypes
void solid(int r, int g, int b, int t);
void fade(int r1, int g1, int b1, int r2, int g2, int b2, int t);
void setup()
{
//empty
}
void loop()
{
//colour sequence instructions
//Example sequence one: Rainbow fade over 12 seconds:
solid(255,0,0,500); // Maintain pure red 1 sec
fade(255,0,0,0,255,0,1500); //fade from red to green over 3 seconds
solid(0,255,0,1000); // Maintain pure green 1 sec
fade(0,255,0,0,0,255,1500); //fade from green to blue over 3 seconds
solid(0,0,255,1000); // Maintain pure blue 1 sec
fade(0,0,255,255,0,0,1500); //fade from blue to red over 3 seconds
}
//function holds RGB values for time t milliseconds
void solid(int r, int g, int b, int t)
{
//map values - arduino is sinking current, not sourcing it
r = map(r, 0, 255, 255, 0);
g = map(g, 0, 255, 255, 0);
b = map(b, 0, 255, 255, 0);
//output
analogWrite(rpin,r);
analogWrite(gpin,g);
analogWrite(bpin,b);
//hold at this colour set for t ms
delay(t);
}
//function fades between two RGB values over fade time period t
//maximum value of fade time = 30 seconds before gradient values
//get too small for floating point math to work? replace floats
//with doubles to remedy this?
void fade(int r1, int g1, int b1, int r2, int g2, int b2, int t)
{
float r_float1, g_float1, b_float1;
float r_float2, g_float2, b_float2;
float grad_r, grad_g, grad_b;
float output_r, output_g, output_b;
//declare integer RGB values as float values
r_float1 = (float) r1;
g_float1 = (float) g1;
b_float1 = (float) b1;
r_float2 = (float) r2;
g_float2 = (float) g2;
b_float2 = (float) b2;
//calculate rates of change of R, G, and B values
grad_r = (r_float2-r_float1)/t;
grad_g = (g_float2-g_float1)/t;
grad_b = (b_float2-b_float1)/t;
//loop round, incrementing time value "i"
for ( float i=0; i<=t; i++ )
{
output_r = r_float1 + grad_r*i;
output_g = g_float1 + grad_g*i;
output_b = b_float1 + grad_b*i;
//map values - arduino is sinking current, not sourcing it
output_r = map (output_r,0,255,255,0);
output_g = map (output_g,0,255,255,0);
output_b = map (output_b,0,255,255,0);
//output
analogWrite(rpin, (int)output_r);
analogWrite(gpin, (int)output_g);
analogWrite(bpin, (int)output_b);
//hold at this colour set for 1ms
delay(1);
}
}
voila et j'ai aussi utiliser l'exemple des servos que j'ai modifier
// Sweep
// by BARRAGAN <http://barraganstudio.com>
// This example code is in the public domain.
#include <Servo.h>
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
void setup()
{
myservo.attach(9); // attaches the servo on pin 9 to the servo object
}
void loop()
{
for(pos = 0; pos < 40; pos += 1) // goes from 0 degrees to 180 degrees
{ // in steps of 1 degree
myservo.write(pos); // tell servo to go to position in variable 'pos'
delay(7); // waits 15ms for the servo to reach the position
}
for(pos = 40; pos>=1; pos-=1) // goes from 180 degrees to 0 degrees
{
myservo.write(pos); // tell servo to go to position in variable 'pos'
delay(7); // waits 15ms for the servo to reach the position
}
}
donc voila mon but est de faire fonctionner les deux programmes en meme temps sauf que je n'arrive pas a ecrire un code viable pour ce programme....
j'espere que vous pourrez m'aidez merci d'avoir lu
