ESP32 communicates with MEGA2560 through uart serial port
Serial data communication is a very popular communication protocol among different data communication. Data communication between ESP32 and Arduino can be done by serial communication. Most microcontrollers can transmit and receive data between them using UART communication.
In this project I have read some data from Arduino Mega TX1 and RX1 from ESP32 pin17 TX2 and pin16 RX2 serially using UART communication protocol.
the ESP32 code is placed on my blog :
