New build.

[Fernando Garcia]

I have an observation for you.

This is my relay board:

As you can see the specification says 125 V / 10 A but, look the PCB trace width:

The width is 3 mm, using this calculator the maximum load for this width is 5.3A.

So no matter if the relay can work at 10 A if the PCB trace can't.

[Christopher Kindig]

Hi, the new relays that I just got have a thicker and wider trace than the others, I asked before I bought them. trace is 5.5mm wide and 2.5oz thick. thank you for the info and, could you post a link to the calculator you showed?

In the first row:
Name: Ferduino
IP Address: (ip you set in ferduino code)

Public port and private port: choose the port you set in Ferduino Mega code

In joy-reef in ip address put the addres you get from the ? in the field.

This should work, let us know

this did not work I have gone back to the d-link router and my own modem.

So new weird issue ferduino board working and online now, thank you so very much for the help Fernando, I have a new issue the ferduino kicked all most all other items off my home network but i will figure that one out.

I have figured out what happend on my network, it was something I forgot to change .

Next part will be to set up 16 relay board 120 volt items and controls as well as codde for PCF.

Ok so new issue was working on some other stuff and now no more Internet connection, when I bring up the serial monitor it give a server ip of 198.128.0.128 whitch is not the server I have it set up for I tried to reboot router and network, then I tried to change port on all three ferduino, router and, joy reef but none worked. I work more with it tomorrow.
I did however have a question about the pins for the chiller and heater I could not PCF8575 to work so I went back to original and was wondering is on when pin is LOW or HIGH?

Hi!

This issue of wrong IP is related with SD card. Check if your card is connected and working fine.

Your relay board should be HIGH to OFF and LOW to ON.

On this case I think better connect the relay board to an ULN2803 so, no needs lose time changing the code.

Wiring:

Best regards.

[Christopher Kindig]

The ULN chip is all redy on the board or do I have to set up?

Ip issue: I will check the sd card when I get home, serial said it was reading ok but that may not be the case?

How hard would it be to add more buttons to menu 2 for service of pumps to turn off, on and automatic.

As far as pump controls I will try that on my own I am not trying to make more work for you.

[Fernando Garcia]

ULN can be used when relays are connected to RJ45 (Relays-1) or you can change on code HIGH to LOW and LOW to HIGH.

This isn't needed when the relays are connected to DB25.

The difficult depends of your ability to learn.

I did a new example, check this topic.

[Christopher Kindig]

Hi Fernando,

I tried the code change for db25 and was not able to get it to work, one question is does the pin configuration stay the same as in you previous post or do all pins become high low switched?

[Fernando Garcia]

Hi!

To DB25 NO need change LOW to HIGH.

First try using this example to make sure that it isn't a problem of wiring.

Code: Select all

#include <Wire.h>
#include <PCF8575.h>


byte address = 0x20;

PCF8575 PCF8575;

void setup()
{
  Serial.begin(38400);
  Serial.println("I'm alive!");

  PCF8575.begin(address);

  for(int i = 0; i < 16; i++)
  {
    PCF8575.pinMode(i,OUTPUT);
  }
}

void loop()
{
  for(int i = 0; i < 16; i++)
  {
    PCF8575.digitalWrite(i, HIGH); // Tun on all pins
    delay(200);
  }
  delay(5000);
 
  for(int i = 0; i < 16; i++)
  {
    PCF8575.digitalWrite(i, LOW); // Turn off all pins
    delay(200);
  }
  delay(5000);
}


Best regards.

[Christopher Kindig]

okay will try.


All work accept the ones that say 5volt GND and Vin.

[Christopher Kindig]

Hi Fernando.

I was able to get the test code that you gave me for PFC8575 to work now I just need to assiggn the pins, I had seen in an other post here you showed how to assign the pins I just remember witch one. Can you repost for me.

Hi Fernando.

Just was wondering how you and Willie changed things for his 5.0 TFT? I have been looking all over the place and can't find any thing. Also how can I shift all C readings to F on all pages, I have figured some out. plus on that same topic when I changed code as shown in Willie's feed I now get high temp alarms.

[Fernando Garcia]

See what Willie did at ProcessMyTouch on case 4.

relays all worked on time I have working with the code to try and get them to work as they should and can't them to come on. then some thing new came up I loaded the test code that you gave to me the other day and none of them would work, so disconnect all but one and the light baerly came on the relay board is hooked to a power supply from a pc and, ferduino is on usb power not sure what to do next. really bummed out at this point. and joy reef is hit and miss weather it will work as well.

[Fernando Garcia]

Hi!

Have you connected GND from Ferduino Mega to GND in the relay board?

Look for this:

Watch on youtube.com

Best regards.

[Christopher Kindig]

when I tried to supply power with Ferduino board it did not work so I was using pc power supply to power 5 volts on the relay board.
Now it is all working again?

[Fernando Garcia]

What you mean?

[Christopher Kindig]

i am not sure what happened but the other night only the lights on the relay board would come on and the relays would not click, but now all is working again, nothing is connected any different so I am not sure what to do some things are not being reliable and it has me very nervous to put on my tank
