```Code ExamplesExample 1: Basic Bluetooth ControlIn this example, we will demonstrate how to control the car's motors using Bluetooth commands sent from a mobile app.```cpp
#include <SoftwareSerial.h>// Bluetooth module pins
#define BT_RX 2
#define BT_TX 3// Motor driver pins
#define LEFT_MOTOR_FORWARD 4
#define LEFT_MOTOR_BACKWARD 5
#define RIGHT_MOTOR_FORWARD 6
#define RIGHT_MOTOR_BACKWARD 7SoftwareSerial btSerial(BT_RX, BT_TX);void setup() {
// Initialize Bluetooth module
btSerial.begin(9600);// Initialize motor driver pins
pinMode(LEFT_MOTOR_FORWARD, OUTPUT);
pinMode(LEFT_MOTOR_BACKWARD, OUTPUT);
pinMode(RIGHT_MOTOR_FORWARD, OUTPUT);
pinMode(RIGHT_MOTOR_BACKWARD, OUTPUT);
}void loop() {
// Read Bluetooth data
if (btSerial.available() > 0) {
char cmd = btSerial.read();// Forward
if (cmd == 'f') {
digitalWrite(LEFT_MOTOR_FORWARD, HIGH);
digitalWrite(RIGHT_MOTOR_FORWARD, HIGH);
}
// Backward
else if (cmd == 'b') {
digitalWrite(LEFT_MOTOR_BACKWARD, HIGH);
digitalWrite(RIGHT_MOTOR_BACKWARD, HIGH);
}
// Left
else if (cmd == 'l') {
digitalWrite(LEFT_MOTOR_BACKWARD, HIGH);
digitalWrite(RIGHT_MOTOR_FORWARD, HIGH);
}
// Right
else if (cmd == 'r') {
digitalWrite(LEFT_MOTOR_FORWARD, HIGH);
digitalWrite(RIGHT_MOTOR_BACKWARD, HIGH);
}
// Stop
else if (cmd == 's') {
digitalWrite(LEFT_MOTOR_FORWARD, LOW);
digitalWrite(LEFT_MOTOR_BACKWARD, LOW);
digitalWrite(RIGHT_MOTOR_FORWARD, LOW);
digitalWrite(RIGHT_MOTOR_BACKWARD, LOW);
}
}
}
```Example 2: Autonomous Obstacle AvoidanceIn this example, we will demonstrate how to use ultrasonic sensors to enable the car to avoid obstacles autonomously.```cpp
#include <NewPing.h>// Ultrasonic sensor pins
#define TRIGGER_PIN 9
#define ECHO_PIN 10// Motor driver pins
#define LEFT_MOTOR_FORWARD 4
#define LEFT_MOTOR_BACKWARD 5
#define RIGHT_MOTOR_FORWARD 6
#define RIGHT_MOTOR_BACKWARD 7// Maximum distance for obstacle detection
#define MAX_DISTANCE 200NewPing sonar(TRIGGER_PIN, ECHO_PIN, MAX_DISTANCE);void setup() {
// Initialize motor driver pins
pinMode(LEFT_MOTOR_FORWARD, OUTPUT);
pinMode(LEFT_MOTOR_BACKWARD, OUTPUT);
pinMode(RIGHT_MOTOR_FORWARD, OUTPUT);
pinMode(RIGHT_MOTOR_BACKWARD, OUTPUT);
}void loop() {
// Read ultrasonic sensor data
int distance = sonar.ping_cm();// Avoid obstacle
if (distance < MAX_DISTANCE) {
// Stop and turn around
digitalWrite(LEFT_MOTOR_FORWARD, LOW);
digitalWrite(LEFT_MOTOR_BACKWARD, LOW);
digitalWrite(RIGHT_MOTOR_FORWARD, LOW);
digitalWrite(RIGHT_MOTOR_BACKWARD, LOW);
delay(500);
digitalWrite(LEFT_MOTOR_BACKWARD, HIGH);
digitalWrite(RIGHT_MOTOR_FORWARD, HIGH);
delay(1000);
}
else {
// Move forward
digitalWrite(LEFT_MOTOR_FORWARD, HIGH);
digitalWrite(RIGHT_MOTOR_FORWARD, HIGH);
}
}
