Dear ALL
I am doing my senor year project and I am working on an arduino uno and an easy vr board along with a servo motor HS755 .
i tried to turn servo motor but it refused to work and the COM window(serial monitor) of the arduino asks for command from group 0 and I give it but it stops right there.
However when I unplug the servo motor, the COM window (serial monitor )asks me to say the commands as it is supposed to do if servo motor is plugged ( asking for a command from group 0 then a command for group 1 ) and when i dont give it a command it keep asking for it the command on and on.
PS: I already tried a code on a LED and it worked perfectly .
this is the motor Code:
#include "Servo.h"
#if defined(ARDUINO) && ARDUINO >= 100
#include "Arduino.h"
#include "SoftwareSerial.h"
SoftwareSerial port(12,13);
#else // Arduino 0022 - use modified NewSoftSerial
#include "WProgram.h"
#include "NewSoftSerial.h"
NewSoftSerial port(12,13);
#endif
#include "EasyVR.h"
Servo myservo;
EasyVR easyvr(port);
//Groups and Commands
enum Groups
{
GROUP_0 = 0,
GROUP_1 = 1,
};
enum Group0
{
G0_ARDUINO = 0,

G1_DEUX = 1,

Serial.begin(9600);
port.begin(9600);
myservo.attach(9);
if (!easyvr.detect())

Serial.println("EasyVR not detected!");

{
easyvr.setPinOutput(EasyVR::IO1, HIGH); // LED on (listening)
Serial.print(" Say a command in Group ");
Serial.println(group);
easyvr.recognizeCommand(group);
do
{
// can do some processing while waiting for a spoken command
}
while (!easyvr.hasFinished());
easyvr.setPinOutput(EasyVR::IO1, LOW); // LED off
idx = easyvr.getWord();
if (idx >= 0)
{
// built-in trigger (ROBOT)
// group = GROUP_X; <-- jump to another group X
return;
}
idx = easyvr.getCommand();
if (idx>= 0)
{
// print debug message
uint8_t train = 0;
char name[32];
Serial.print("Command: ");
Serial.print(idx);

{
case G1_UN:
