Generate Single Phase Or Three Phase Sine wave by Arduino

You can generate single phase or three phase 50 Hz Sine Wave through simple coding of Arduino.  The code link is given  here click to download on the link  http://www.areptone.in/arduino/Graph/graph.pdf   or  http://www.areptone.in/adeebraza/sinewavecode.pdf    to see the code in details.

Code:-

// Formule  y(t) = A sin(wt +p)

// Where; A = Amplitude, w =Angluar Frequency. t = Time , p =Phase Difference

// Frequenvy = 50Hz, 3 Phase R Y B, Phase Angle Difference = 120 degree

// R(t) = A sin ((Angular Frequency * time)+ Phase Angle Difference)

// Y(t) = A sin ((Angular Frequency * time)+ Phase Angle Difference)                                     //  B(t) = A sin ((Angular Frequency * time)+ Phase Angle Difference)

// Programmed By Mr. Adeeb Raza

int R= 9     //R Phase at pin no.9

int Y=10;   //Y Phase at pin no.10

int B=11;  //B Phase at pin no.11

void setup() {

Serial.begin (9600);

pinMode(R, OUTPUT);

pinMode(Y, OUTPUT);

pinMode(B, OUTPUT); }

void loop() {

for (int t=0; t<20; t++){ // one cycle 360 degree movement in 20 mili seconds

float R = 2.5* sin ((50*t)+0);    // R Phase Zero Degree

float Y = 2.5* sin ((50*t)+120);  // Y Phase 120 Degree

float B = 2.5* sin ((50*t)+240);  // B Phase 240 Degree

digitalWrite(9, OUTPUT);          // R phase Output on pin No. 9

digitalWrite(10, OUTPUT);        // Y phase Output on pin No. 10

digitalWrite(11, OUTPUT);        // B phase Output on pin No. 11

Serial.print(R); Serial.print(” “);

Serial.print(Y); Serial.print(” “);

Serial.print(B); Serial.println(” “);

delay(1);

}

}

// End code
