  sendOBD2Request("010D"); // OBD2 PID for vehicle speed
  String response = readOBD2Response();
  Serial.print("Vehicle Speed: ");
  Serial.println(response);
  delay(2000); // Wait 2 seconds before sending the next request
}
  • Explanation:
    • This code sends a request for vehicle speed (PID 010D) and prints the response to the serial monitor.

5.5. Using the OBD2 Library:

  • Code:

    #include <SoftwareSerial.h>
#include <OBD2.h>

// Define RX and TX pins for the software serial port
#define RX_PIN 16
#define TX_PIN 17

// Create a software serial object
SoftwareSerial OBDSerial(RX_PIN, TX_PIN); // RX, TX

OBD2 obd;

void setup() {
  Serial.begin(115200);
  OBDSerial.begin(38400); // OBD2 default baud rate

  obd.begin(OBDSerial);
