In this tutorial, you’ll learn how to use ESP-NOW communication protocol to send data from one ESP32 to multiple ESP32 or ESP8266 boards (one-to-many configuration). The boards will be programmed using Arduino IDE. To get started with ESP-NOW on the ESP32 or ESP8266, read the follow...
To write data to the Serial Monitor, you use the print() or println() methods on the Serial instance. Serial.println("ESP32 is ready. Please enter a message:"); You can also send data from the Serial Monitor to the ESP32. To read that data, you can use the read() method. To ...
Earlier we looked at a method ofprogramming ESP8266 to send sensor data directly to Google Sheetswithout using any third party modules. Now, we will expand that a little bit and learn to send an email as well as a text message (SMS) using ESP8266. In this demo, we will configure our ...
