Nextion+Arduino Tutorial #2 Sending Data To Arduino

I show a few examples on how you can send data from the Nextion display to the Arduino board and vice versa. This time I use the nextion library, but only to receive data from the display. To send data to the display I still prefer sending it without using the library (like I showed on my 1st tutorial), so this tutorial is a mix of both techniques.

Note: On the video I said "microseconds", but it's actually milliseconds.

What model is your display?
It's the 3.5" enhanced version NX4832K035.

I’m remaking the check control display in my 1985 BMW 635CSi to look modern and impressive. I have a lot to do and am currently brainstorming workflow charting all of the processes before designing my screens in CorelDraw. I’ve made a few but it’s super challenging. I’ll be referring to your videos as I complete the build. Keep your videos coming. They’re a HUGE HELP and I’m very grateful.

REALLY well made video! I love the effort you have put into making it "to the point" and focusing on the difficult parts

[CleancutCampers]

Thank you so much for this. I've been searching so hard for the information in this video. Keep up the good work.

Man you saved my day with that Send Component ID thing. I appreciate you

[leeharrington]

This has been a big big help - so many thanks for this!!

Thanks for the great video! However I'm having issues with a Teensy 3.6 and a Nextion 3.5". In one way I can send text info from the teensy to the display and change the text inside a button, but nothing happens whenever I press buttons I created... I've tried everything :(

[REXONCROSS]

Thanks a lot for your help mate. This is the perfect tutorial for all my questions.

you are best so far in explaining the nextion displays.thank you for all your hard work and R&D. please make more videos !!

[becky]

Hiya,
Thank you for taking the time to post the videos. I have a large RC project that include touch screen to control multiple distances on a single stepper.

[eligijuspranskunas]

your code inside with explanations is very good and clear, thanks a lot!

[sirthomas]

You were sent from coding heaven. Thanks a million. Now I have a chance. Thats a lot of work you've saved me.

[ohmedarick]

Thank you for your time and effort. Great video!!! Help me understand better the nextion library.

[NikolayAgopyan]

Thank you for the great tutorial, answered LOTS of questions!

[MyViewsOfCornwall]

Many thanks, excellent presentation and commented coding. I hadn't figured out there is a PushCallback as I'd based my work on the CompButton example (uses just Pop) so I'd spent a couple of hours wondering why buttons only invoked the Arduino routine on release... So wish YouTube had suggest your channel sooner before several others. Thank you again.

Finally someone who puts the sketch to help and not just a movie to show that it is cool
Thank you
