Help me code for send sensor data from Arduino Mega to NodeMcu ESP8266 and to Blynk app

Help my project, I want send sensor data (Ds18b20, SHT10, BH1570, TDS Meter) from Arduino Mega 2560 to NodeMCU Esp 8266 and to show on app Blynk. Help me for code, communicate between 2 device and can give me example codes for this project. I’m newbie, thank you very much from your help. Looking forward to receiving feedback soon from you.

What does the photo you posted have to do with the project you described?

Yes, ís it

What is it??

I’m sorry, but this doesn’t add-up to me.
You’re using a custom circuit board that contains 17 relays, a NodeMCU, some other boards that might include an Arduino, what looks like a SIM800 modue and some sensors.

You say:

and ask for code to communicate between an Arduino Mega and a NodeMCU, and make no mention of Blynk.

There’s clearly much more to this project than you describe, and it’s far from a newbie project.

It feels to me like you’re a troll, and I’m tempted to suspend your account. Since joining the forum 12 days ago you’ve read 2 topics for a total of 12 minutes. Not the sort of behaviour I’d expect from someone who was a newbie and keen to learn.

If you aren’t a troll and genuinely want some assistance with an actual Blynk related query then I’d suggest that you provide more information about what it is that your project is about, where Blynk fits in, and what work you’ve done on the project so far.
