Greetings! Thankyou for this wonderful tutorial of yours. I have a question, though. I have a project set up like this: a relay controlled by a nextion display containing two pages, the first one is for the logo and the second is for the buttons. For the buttons, I use a dual-state-butons to control the status of the relay so when you click the button, the status of the relay triggers ON and persists until I click the button again. My problem is that when I go back to the first page containing the logo while a button is clicked on the second page, the status of the button in the second page resets while my relay continues to be ON. So it seems the use of dual state buttons is compromised. Do you know what should i do to to fix my problem? Thank you for your insight.
You need change the scope from local to global. You should see this in the attributes of the dual state button. thank you for the kind words and good luck with your project.
This is such a great tutorial! Im having touble finding the files for download. I found the video in the old website, but there are no links for downoading files, am I looking for them in the wrong place?
That is an older video. I don't have all the files for every video loaded. But I will load them as people request. I just uploaded the files. the should be available now. I could not remember which Arduino file I used in the video. I have two uploaded. I hope one will work for you. If not let me know and I will try to figure out how to help better. thank you for your kind words.
Hi. great work with all the videos! Hope you can help... I am trying really hard to find a video to see 2 dual-state buttons turning on 2 separate LEDs. This is all I will need in my project for now, but I can't find how to do this. I find many videos of how to use a dual-state button to turn on 1 LED, but nowhere about multiple dual-state buttons... Please help....

hi, I want to trigger Nextion button from arduino, not per hand on the display. do you know, how to trigger dual button from arduino to Nextion display.
Hi, sorry if I persist with the questions but I can't understand, if I only have a "dual state button" how can I send the two states separately to arduino to make him do a different action for each state? I have performed many tests but I cannot understand how to do it. I'm a tough head :-)
Ok, I found the solution, I don't know if it's right or it can be done better but it works, just add these lines in Nextion Editor to send the two different states: if(bt1.val==1) { print "vaporeON" }else if(bt1.val==0) { print "vaporeOFF" }
@@CheapControls As I uderstand, the difference in the case above you can program whatever you want inside the if and that will be done on the nextion side before sending something to the arduino, and in the case on the video the nextion sends a 0 or a 1 when the button is pressed and then you can program whatever you want to do with that on the arduino side, right? Sorry for the many questions, Im just beggining to understand how this works
@@DianaMartinez-su6jh That logic is correct. but I would not just send a 0 or 1. I send it in a key-value pair with a beginning and end parameter. like C:CTST0? starting parameter C:C then the command being TST then the value of 0 then the ending delimiter of ?
hi there I copy and paste the code_5 from the text file to Arduino, and verify it show this message (error: 'Serial2' was not declared in this scope) I don't know what I have missed! Can you please help me?
My videos use a mega. you will need to add a library and alter the code a bit for the UNO. The mega has extra built in serial ports that the UNO does not have. It is not difficult to use with an UNO. I will post a second reply here with the library. I will also post an different file for the UNO. I am not on my development laptop but will be later.
@@daryl7237 I have the code up at Cheap Controls for download(The links look identical but if you hover over them you will see one will say UNO in the file name). I will work on creating a separate image for UNO versus MEGA. You will notice two new lines at the top of the code. This is for the softserial library. Then in the code Serial2 is replaced with mySerial. You will use pins 2 and 3 for the additional Serial Port.

Do you want a on/off button on the nextion to control and LED on the Arduino? I just want to be clear on your question.
