Code mode pumps alternated [SOLVED]

[Simone Sandonati]

hello Fernado

I wanted to know if it was possible to create a way of wavemaker pumps alternated in this way

Pump 1: 0
pump 2: 0 to max then returns to 0

pump 1: 0 to max then returns to 0
pump 2: 0

and so on ....

I can not create the code

[Fernando Garcia]

Hi!

All is possible if you want.

Best regards.

[Simone Sandonati]

Could you help me I did some tests but I do not work

thank you

[Fernando Garcia]

Maybe, if you show me what you are doing.

[Simone Sandonati]

Code: Select all

    value = int(128 + 127 * sin(2  *  PI / periodo * times));
    Pump1PWM = 255 - value;
    Pump2PWM = 0;

    Pump1PWM = 0;
    Pump2PWM = 255 - value;


[Fernando Garcia]

On this way Pump1PWM never will be different of zero.

You need add conditions to alternate between this two cases.

By example during how many seconds the values will be Pump1PWM = 255 - value and Pump2PWM = 0.

Adding a Serial.println(Pump1PWM); and Serial.println(Pump2PWM); can help you learn how it change of value.

sorry I can not understand where I enter the Serial.println

Could you help me?

thank you

[Simone Sandonati]

I did many tests but I can not do this function

please help me?

[Simone Sandonati]

but serialprint not need to write the messages on the display?

I can not understand how I should set up the command

[Fernando Garcia]

Hi!

Try learn the basic first.

Google it.

Best regards.

[Simone Sandonati]

should I use a Millis right?

but I do not know how to set it up

help me?

[Simone Sandonati]

do not help me please ????

[Fernando Garcia]

Hi!

After all this time let me see the code that you wrote.

Best regards.

[Simone Sandonati]

I am still stuck to the code I posted above I do not know how to move forward and for this I ask help

thank you

[Fernando Garcia]

Hi!

I really think that you only want the code done.

Try this:

Ferduino tab:

Code: Select all

// Global variables
unsigned long millis_step = 0;
byte step = 0;
int step_time = 1000; // milliseconds


Wavemaker tab:

Code: Select all

  else if (modo_selecionado == 5)
  {
    if (step == 0)
    {
      if ((millis() - millis_step) > step_time)
      {
        Pump1PWM += 1;
        Pump2PWM = 0;
        millis_step = millis();
      }
      if (Pump1PWM == 255)
      {
        step = 1;
      }
    }
    else if (step == 1)
    {
      if ((millis() - millis_step) > step_time)
      {
        Pump1PWM -= 1;
        Pump2PWM = 0;
        millis_step = millis();
      }
      if (Pump1PWM == 0)
      {
        step = 2;
      }
    }
    else if (step == 2)
    {
      if ((millis() - millis_step) > step_time)
      {
        Pump1PWM = 0;
        Pump2PWM += 1;
        millis_step = millis();
      }
      if (Pump2PWM == 255)
      {
        step = 3;
      }
    }
    else if (step == 3)
    {
      if ((millis() - millis_step) > step_time)
      {
        Pump1PWM = 0;
        Pump2PWM -= 1;
        millis_step = millis();
      }
      if (Pump2PWM == 0)
      {
        step = 0;
      }
    }
  }


It will replace manual mode so the buttons + and - on touch will be useless.

It's very basic and only with this tutorial is possible write this function: https://www.arduino.cc/en/Tutorial/BlinkWithoutDelay

Please do not ask me to make other custom function for you.

Best regards.

Thanks for your help

I wanted to decrease the step_time 1000 milliseconds to 10 millisecond to increase the speed of climb and descent

I located a problem if I'm okay in wavemaker screen works well if I move on the home screen does not keep him more step_time set but charged on a much more high speed and the pumps are only small movements

I controlled via serial monitor effects the speed of the count and very fast

I do not understand why it seems that outside the screen wavemaker does not take account of step_time

thank you

[Fernando Garcia]

Hi!

I can't see any problem since 10 milliseconds is very fast even and the PWM keeps high during a small amount of time.

The speed seems smaller in wavemaker screen because the controller is spending time to update the screen all time and in home screen it doesn't happens.

Best regards.

I connected the pumps when they step to the start menu the pumps do not follow more times and go much faster do not know if I explained

if I use the mode 1 or 2 etc. the defect does not occur

step_time if I put it in 1000 operates all right

but quersto way pome go real slow I would like the mode 1 and 2 speed but if I lower the time to 10 I leave the screen in wavemaker works well if I go back to the home screen changes speeds very strong as if not taking the spet_time

[Fernando Garcia]

I don't understand, a video can help.
