Hello people. I need to send an receive data from arduino mega to my nodemcu esp8266 lolin. I succesfully send and receive data with serial comunication. I can read data in serial monitors. But the problem is: i want to send data from arduino mega to esp , receive data on esp, and post it on adafruit site. So how i can receive the data from arduino mega, (a lot of data. Temperatura, gas level etc) and read it corectly with esp? Thanks!!
why not through Serial?
Read this Serial Input Basics to see how to receive data correctly, then parse the data and send using whatever adafruit library to reach their site
