Jumper Wires and BreadboardSoftware ComponentsArduino IDE (version 1.8.x or later)Code Examples### Example 1: Obstacle Avoidance using Ultrasonic SensorIn this example, we will demonstrate how to use the ultrasonic sensor to detect obstacles and avoid them.Code:
```c++
const int trigPin = 2; // Ultrasonic sensor trig pin
const int echoPin = 3; // Ultrasonic sensor echo pin
const int leftMotorForward = 4; // Left motor forward pin
const int leftMotorBackward = 5; // Left motor backward pin
const int rightMotorForward = 6; // Right motor forward pin
const int rightMotorBackward = 7; // Right motor backward pinvoid setup() {
pinMode(trigPin, OUTPUT);
pinMode(echoPin, INPUT);
pinMode(leftMotorForward, OUTPUT);
pinMode(leftMotorBackward, OUTPUT);
pinMode(rightMotorForward, OUTPUT);
pinMode(rightMotorBackward, OUTPUT);
}void loop() {
int duration, distance;
digitalWrite(trigPin, LOW);
delayMicroseconds(2);
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);
duration = pulseIn(echoPin, HIGH);
distance = duration 0.034 / 2;if (distance < 20) {
// Obstacle detected, turn around
digitalWrite(leftMotorForward, HIGH);
digitalWrite(rightMotorBackward, HIGH);
delay(500);
digitalWrite(leftMotorForward, LOW);
digitalWrite(rightMotorBackward, LOW);
} else {
// Move forward
digitalWrite(leftMotorForward, HIGH);
digitalWrite(rightMotorForward, HIGH);
}
delay(50);
}
```
Explanation:This code uses the ultrasonic sensor to detect obstacles in front of the car. The sensor sends out a high-frequency sound wave and measures the time it takes for the wave to bounce back. If the distance is less than 20cm, the car turns around to avoid the obstacle. Otherwise, it moves forward.### Example 2: Line Following using Infrared SensorIn this example, we will demonstrate how to use the infrared sensor to follow a black line on a white surface.Code:
```c++
const int infraredPin = A0; // Infrared sensor pin
const int leftMotorForward = 4; // Left motor forward pin
const int leftMotorBackward = 5; // Left motor backward pin
const int rightMotorForward = 6; // Right motor forward pin
const int rightMotorBackward = 7; // Right motor backward pinvoid setup() {
pinMode(infraredPin, INPUT);
pinMode(leftMotorForward, OUTPUT);
pinMode(leftMotorBackward, OUTPUT);
pinMode(rightMotorForward, OUTPUT);
pinMode(rightMotorBackward, OUTPUT);
}void loop() {
int infraredValue = analogRead(infraredPin);
if (infraredValue < 500) {
// Line detected, move forward
digitalWrite(leftMotorForward, HIGH);
digitalWrite(rightMotorForward, HIGH);
} else {
// Line not detected, turn around
digitalWrite(leftMotorBackward, HIGH);
digitalWrite(rightMotorBackward, HIGH);
delay(500);
digitalWrite(leftMotorBackward, LOW);
digitalWrite(rightMotorBackward, LOW);
}
delay(50);
}
```
Explanation:This code uses the infrared sensor to detect the black line on the white surface. The sensor reads the reflected infrared light and outputs a value between 0 and 1023. If the value is less than 500, the car moves forward. Otherwise, it turns around to search for the line.### Example 3: Accelerometer-based Tilt ControlIn this example, we will demonstrate how to use the accelerometer to control the car's movement based on its tilt.Code:
```c++
const int xPin = A1; // Accelerometer x-axis pin
const int yPin = A2; // Accelerometer y-axis pin
const int leftMotorForward = 4; // Left motor forward pin
const int leftMotorBackward = 5; // Left motor backward pin
const int rightMotorForward = 6; // Right motor forward pin
const int rightMotorBackward = 7; // Right motor backward pinvoid setup() {
pinMode(xPin, INPUT);
pinMode(yPin, INPUT);
pinMode(leftMotorForward, OUTPUT);
pinMode(leftMotorBackward, OUTPUT);
pinMode(rightMotorForward, OUTPUT);
pinMode(rightMotorBackward, OUTPUT);
}void loop() {
int xValue = analogRead(xPin);
int yValue = analogRead(yPin);
if (xValue > 500) {
// Car is tilted forward, move forward
digitalWrite(leftMotorForward, HIGH);
digitalWrite(rightMotorForward, HIGH);
} else if (xValue < 400) {
// Car is tilted backward, move backward
digitalWrite(leftMotorBackward, HIGH);
digitalWrite(rightMotorBackward, HIGH);
} else if (yValue > 500) {
// Car is tilted left, turn left
digitalWrite(leftMotorForward, HIGH);
digitalWrite(rightMotorBackward, HIGH);
} else if (yValue < 400) {
// Car is tilted right, turn right
digitalWrite(leftMotorBackward, HIGH);
digitalWrite(rightMotorForward, HIGH);
}
delay(50);
}
```
Explanation:This code uses the accelerometer to measure the car's tilt and control its movement accordingly. The x-axis and y-axis values are read from the accelerometer and used to determine the car's tilt direction. Based on the tilt, the car moves forward, backward, left, or right.Note: These examples are for illustrative purposes only and may require modifications to work with your specific setup. Make sure to adjust the pin connections and sensor calibrations according to your IoT and DIY Smart Car Starter Kit.
