The ESP32-S3 can communicate with an Arduino UNO via UART, I2C, or SPI. Below is an example of using UART for communication:
#include <SoftwareSerial.h>
// Define RX and TX pins for communication with ESP32-S3
SoftwareSerial espSerial(10, 11); // RX = Pin 10, TX = Pin 11
void setup() {
Serial.begin(9600); // Initialize serial monitor
espSerial.begin(115200); // Initialize communication with ESP32-S3
Serial.println("Arduino is ready to communicate with ESP32-S3.");
}
void loop() {
// Send data to ESP32-S3
espSerial.println("Hello from Arduino!");
// Check if data is available from ESP32-S3
if (espSerial.available()) {
String data = espSerial.readString();
Serial.println("Received from ESP32-S3: " + data);
}
delay(1000); // Wait for 1 second
}
