hi DJ it would not do a right()?

Strange. Works in my test when I wrote it.

hi DJ i'll play with the timing of the scan etc.

Okie

Ah you know what? Maybe don't have it move from 10 to 80 because that might be what's happening. Have it move from 10 to 40. The. 40 to 80. Then 80 to 40. Then 40 to 10.

Repeat

Also, if you get the latest ARC... There is a C# example for a radar control. Look under File -> Examples -> Script C Radar Control

hi DJ Thanks i did a little mod

1. it move forward after turning
2. scan rate is faster
3. it works

using System;
using System.IO;
using System.Windows.Forms;
using EZ_B;

namespace VName {

  public class VClass {

    public void Main(EZB ezb0, EZB ezb1, EZB ezb2, EZB ezb3, EZB ezb4) {

      bool dir     = true;
      bool weMoved = false;

      ezb0.Servo.SetServoPosition(Servo.ServoPortEnum.D5, 10);
      
      while (true) {
      
        int servoPos = ezb0.Servo.GetServoPosition(Servo.ServoPortEnum.D5);
        int distance = ezb0.HC_SR04.GetValue(Digital.DigitalPortEnum.D0, Digital.DigitalPortEnum.D1);
 
        if (distance  40)
            ezb0.Movement.GoRight();
          else if (servoPos  80)
            dir = false;
        
          if (servoPos < 10)
            dir = true;

          ezb0.Servo.SetServoPosition(Servo.ServoPortEnum.D5, servoPos);
        }

        System.Threading.Thread.Sleep(250);
      }
    }
  }
}
