You're welcome! I'm glad I could help. If you have any more questions or need further assistance as you work on your project, feel free to reach out. Good luck with your robot, and have fun building and programming!

To control the virtual servos V21 and V22 with variable speed based on joystick input and ensure proper stopping, you need to use the correct variable that represents the joystick's Y-axis value. In ARC, joystick values are typically stored in global variables like $JoystickY1, which you can use to determine the speed and direction of the stepper motor.

The $JoystickY1 variable will range from -1 (full down) to 1 (full up), with 0 being the center position. You'll need to map this range to your stepper motor's speed range and convert it into pulses.

Here's an updated JavaScript code snippet for ARC that includes mapping the joystick value to a pulse rate and ensuring the stepper motor stops correctly:

// Function to pulse the stepper motor for movement
function pulseStepper(directionPin, pulsePin, speed) {
  // Set the direction based on the sign of the speed
  digital.set(directionPin, speed >= 0);

  // Calculate the pulse rate based on the absolute speed value
  var pulseRate = Math.abs(speed) * 500; // Adjust the multiplier to get the desired pulse rate

  // Pulse the stepper motor at the calculated pulse rate
  for (var i = 0; i < pulseRate; i++) {
    digital.set(pulsePin, true);
    sleep(1); // Wait for 1 millisecond (adjust as needed for your stepper driver)
    digital.set(pulsePin, false);
    sleep(1); // Wait for 1 millisecond (adjust as needed for your stepper driver)
  }
}

// Forward movement function
function forward() {
  var joystickValue = getVar('$JoystickY1'); // Get the joystick Y-axis value
  var speed = map(joystickValue, -1, 1, -500, 500); // Map joystick value to speed range
  pulseStepper(D21, D22, speed);
}

// Reverse movement function
function reverse() {
  var joystickValue = getVar('$JoystickY1'); // Get the joystick Y-axis value
  var speed = map(joystickValue, -1, 1, -500, 500); // Map joystick value to speed range
  pulseStepper(D21, D22, -speed);
}

// Stop movement function
function stop() {
  // Stop pulsing the stepper motor by not calling the pulseStepper function
  digital.set(D21, false);
  digital.set(D22, false);
}

// Map function to convert range
function map(value, fromLow, fromHigh, toLow, toHigh) {
  return (value - fromLow) * (toHigh - toLow) / (fromHigh - fromLow) + toLow;
}

In this code, the map function is used to convert the joystick value to a speed range suitable for your stepper motor. The pulseStepper function is then called with this speed to move the stepper motor.

The stop function sets both control pins to low to ensure the stepper motor stops moving.

Regarding the pulse rate, the pulseRate variable is calculated by multiplying the absolute speed value by a factor that determines how many pulses per second you want to achieve. Adjust the multiplier to match your stepper motor's capabilities and the desired pulse rate.

Please note that the sleep duration in the pulseStepper function may need to be adjusted to achieve the correct pulse rate for your stepper motor. The current setup with sleep(1) is a placeholder and may not provide the exact timing you need.

Make sure to test this code and adjust the parameters to match the behavior of your stepper motor and driver. If your stepper motor driver has specific requirements for pulse width or timing, you'll need to modify the sleep duration accordingly.

@Athena continuing on this previous conversation, this is very helpful information but could you refer to the StepperServo skill and revise your answer  // Stop movement function function stop() { // Stop pulsing the stepper motor by not calling the pulseStepper function digital.set(D21, false); digital.set(D22, false); because it is sending the information to the Arduino for pin 2 and pin 3 for pulse and direction.

Certainly! If you're using the StepperServo skill and need to control the stepper motor using virtual ports V21 and V22, you'll want to send commands to the Arduino that is managing the stepper motor. The Arduino will interpret these commands to control the pulse and direction pins.

Here's a revised version of the JavaScript code snippet for ARC that sends the appropriate commands to the Arduino through the StepperServo skill:

// Function to control the stepper motor speed and direction
function controlStepper(speed) {
  // Map the joystick value to a speed range and send the command to the StepperServo skill
  // Positive speed for forward, negative speed for reverse
  var command = (speed >= 0) ? 'Forward' : 'Reverse';
  var absoluteSpeed = Math.abs(speed); // Ensure the speed value is positive

  // Send the speed and direction command to the StepperServo skill
  ControlCommand('Stepper Servo', command, absoluteSpeed);
}

// Forward movement function
function forward() {
  var joystickValue = getVar('$JoystickY1'); // Get the joystick Y-axis value
  var speed = map(joystickValue, -1, 1, -500, 500); // Map joystick value to speed range
  controlStepper(speed);
}

// Reverse movement function
function reverse() {
  var joystickValue = getVar('$JoystickY1'); // Get the joystick Y-axis value
  var speed = map(joystickValue, -1, 1, -500, 500); // Map joystick value to speed range
  controlStepper(-speed); // Negate the speed for reverse direction
}

// Stop movement function
function stop() {
  // Send the stop command to the StepperServo skill
  ControlCommand('Stepper Servo', 'Stop');
}

// Map function to convert range
function map(value, fromLow, fromHigh, toLow, toHigh) {
  return (value - fromLow) * (toHigh - toLow) / (fromHigh - fromLow) + toLow;
}

In this code, the controlStepper function sends a command to the StepperServo skill with the desired speed. The forward and reverse functions map the joystick value to a speed range and call controlStepper with the appropriate speed. The stop function sends a 'Stop' command to the StepperServo skill to halt the stepper motor.

Please ensure that the ControlCommand syntax matches the actual commands accepted by the StepperServo skill. The command variable should be set to the correct command names that the StepperServo skill expects for forward, reverse, and stop actions.

The map function is used to convert the joystick value to a speed range suitable for your stepper motor. Adjust the map function parameters to match the speed range that your stepper motor and Arduino code can handle.

Remember to replace 'Stepper Servo' with the actual name of your StepperServo skill in the project if it's different. The absoluteSpeed variable should be calculated based on how your Arduino code interprets speed values. Adjust the mapping range accordingly to ensure the stepper motor operates within its capabilities.

The question doesn’t make any sense so she can’t help you. It’s an impossible question.  Such as, can you make an engine into a car so I can use it in a car?

To make a movement panel, you need to make a robot skill. The manual to do so is in the support section and does not use JavaScript. JavaScript is not a complied programming language for making software - it’s a scripting language.

you cannot make a Movement Panel that works in a movement panel. Those two things are the same thing and even I don’t understand for question

ill probably be best to answer this by saying a stepper motor robot skill CANNOT be used in a Movement Panel because it works as a servo. A servo has a finite range of movement - which is why you’re experiencing what you’re experiencing - that's by design.

your best option is to connect a stepper driver to an ezb digital port. Then, write a loop in a custom Movement Panel v2 to move the steppers for each direction. This has been discussed many times in previous duplicate questions that you’ve asked. I think you’re stuck assuming a different response or maybe you’re not fully sure what the question is hehe cause I’ve been there before.

but the answer is so what Athena had said in the last twenty times youve posted about this AND she’s even gave you code for it the past to control a stepper directly from an ezb in a custom Movement Panel v2.

please read what a Movement Panel is before continuing. Click on the word Movement Panel from anywhere you see it highlighted.

This is the first time that I have seen this statement   ill probably be best to answer this by saying a stepper motor robot skill CANNOT be used in a Movement Panel because it works as a servo. A servo has a finite range of movement - which is why you’re experiencing what you’re experiencing - that's by design. Now that I know that it won't work like this and since I have been poking around asking question and found the proper variables to work with I think can now write the loop that you are talking about. Sometimes I ask similar questions on purpose so that I can find hidden answers in her answers. Bear with me it's a process.

As soon as I heard "you cannot make a Movement Panel that works in a movement panel." it clicked. I figured it out and now I have the Movement Panel working great.
