Hi,Can you maybe describe the case in what you want to use it? This will help me to give you the best answer as I have a couple of scenarios running through my head, but I am not sure which one will suit your needs.Regards,Gideon

Thanks. I will make the change.

Hello. I am not at home to test it now, but try everything the same except change the one line to:SendThis.concat(""active"");The difference being using double inverted commas. Regards, Gideon

Hi,I am not entirely sure what you mean. Please direct me to where in the code your problem is?Regards,Gideon

Hi,Thanks for sharing your code here. I have a mega too, so perhaps I'll use your code sometime. Hopefully it will be of use to others too!

I am glad it was of use to you.

Thank you for the kind words. I'm glad it was useful to you.

Hi,I hope the code works well. You are absolutely right about the power thing. I will change that soon.Regards,Gideon

Hi,That looks cool. I am glad you could expand it for your own purpose.Regards,Gideon

Hi,When in the Nextion editor, look at your button's properties. Properties in bold and green are the only properties you can set from the Arduino. The bco (colour) property of the button is green but not bold, so I suspect that you cannot change its colour.Nextion has a dual state button however. It has a property "val" that indicates the button state and is editable via the Arduino. In short it is possible, but you'll need to use a dual state button of which you'll change the "val" property with the Arduino to get different colours.Regards,Gideon

Hi,I am very happy to hear that you benefited from this. Getting started with the Nextion was a major problem for me as well. As soon as I added the library the sketch wouldn't compile.I also did a part 2 and 3 of working with the Nextion. Part 3 is capable of handling more complex interfaces.Regards,Gideon

Hi, thanks for this. I needed to know how to use the sensor. Thanks to you I do now!

Hi,Yes Peltiers draw a lot of power. How well did it work while the batteries were ok?

Hi,You are quite right. I've even read that Peltiers can be as inefficient as 2%! Let's see how the tests go, but my hopes aren't too high.

Thanks, without you I'd be lost!
