Hi Isidora!

Welcome back.

I believe you are talking about this code.

This messages are warnings not errors.

You can fix some of this warnings adding (char*) before every text in myGLCD.print function.

Hi!

Happy to know you have found the root of the problem.

When possible please show us the integration of your Ferduino controller with your home automation.

For now I"ll close this topic.

Best regards.

Hi!

This error is from Mosquitto log?

Best regards.

I think the problem is here:



Increase the time in the ESP-link interface.

Hi!

For now I have no idea.

Look the debug log on ESP-Link to try find some useful information.



Best regards.

Hi!

What you can see on serial monitor?

Looks like ESP-link or Ferduino code is closing the connection instead keep alive.

Best regards.

Hi! This ULN module will give more problem than solution. Separated module require more wires and more wires are susceptible to bad contact and so on. The circuit for dosing pumps or fans is very simple and can be assembled in the prototype shield. Maybe this picture can make the things more clear t...

Hi!

This module can be used but keep in mind there's no control in the current available for LED.

To control the current you should put resistor in serie with LED.

Best regards.

Hi!

I think the initial question was answered so I will close this topic.

Best regards.

Hi! Welcome Jean! I have no experience with any pH circuit other than from Atlas Scientific. You can use any cheap pH circuit compatible with Arduino but you have to adjust Ferduino code by yourself. The only help you will get from me about this part is available here . Just pay attention that the v...

Hi! I found a better way to add WiFi to Ferduino. This is not a $5 solution but at least no soldering is required and the build will be more clean. https://www.ferduino.com/forum/gallery/image.php?album_id=11&image_id=753 This board by RobotDyn has built-in an ESP8266. You can follow the video a...

1 - Make the selection of ethernet shield or ESP8266 more clear.
Now user should uncomment USE_ETHERNET_SHIELD or USE_ESP8266 to enable web interface.

You should mark the option "Align image" as left, center or right leaving as default will give you this error. It seems good but I think you could make a single PCB to connect the ISO board, rj45 and multiplexer to avoid bad connections in wires. Also the box could be so much smaller. As d...

Hi! This feature is in my task list but now I have only stamps 4.X. Is very complicated to add code without hardware to test. Stamps 4.x are obsolete since long time so add code for it will be waste of time. Normally is not needed disassembly the controller, is needed just change the code and it sho...

Hi!

After long time I'm revisiting this subject.

The PCB is ready now I have to place the components.





Best regards.

Hi!

Glad to hear!

Hi!

ESP8266 12F is the microcontroller used on NodeMCU.

This "experience plate" is more known as breadboard or protoboard.

Best regards.

What's the reason to use ESP8266 12F instead NodeMCU? Are you doing a custom board?

The "experiment board" you are talking about is like this?

Hi! You have to leave the code in this way: #define ETHERNET_SHIELD #define USE_ESP8266 Then look for this message on serial monitor: Syncing Arduino and ESP8266... Synced! Or Syncing Arduino and ESP8266... Syncy failed!! Is not needed connect probes to controller. Best regards.

Hi!

No, just uncomment this line:



After install the code open the serial monitor and set the baud rate to 38400 then check if ESP and Arduino are synced.

Best regards.
