The component is also compatible with popular robotics libraries and frameworks, such as Arduino IDE and Robot Operating System (ROS).Code Examples### Example 1: Basic Motor Control using Arduino IDEIn this example, we will demonstrate how to control the motor speeds using the Arduino IDE.```c
const int leftMotorForward = 2; // Pin 2: Left Motor Forward
const int leftMotorBackward = 3; // Pin 3: Left Motor Backward
const int rightMotorForward = 4; // Pin 4: Right Motor Forward
const int rightMotorBackward = 5; // Pin 5: Right Motor Backwardvoid setup() {
pinMode(leftMotorForward, OUTPUT);
pinMode(leftMotorBackward, OUTPUT);
pinMode(rightMotorForward, OUTPUT);
pinMode(rightMotorBackward, OUTPUT);
}void loop() {
// Move forward
digitalWrite(leftMotorForward, HIGH);
digitalWrite(rightMotorForward, HIGH);
delay(1000);
// Move backward
digitalWrite(leftMotorBackward, HIGH);
digitalWrite(rightMotorBackward, HIGH);
delay(1000);
// Stop
digitalWrite(leftMotorForward, LOW);
digitalWrite(rightMotorForward, LOW);
digitalWrite(leftMotorBackward, LOW);
digitalWrite(rightMotorBackward, LOW);
delay(1000);
}
```### Example 2: Line Follower using Python and OpenCVIn this example, we will demonstrate how to use the DIY 2WD Mini Round Robot Car as a line follower using Python and OpenCV.```python
import cv2
import serial# Initialize the serial connection
ser = serial.Serial('COM3', 9600) # Replace 'COM3' with your serial port# Initialize the OpenCV camera
cap = cv2.VideoCapture(0)while True:
ret, frame = cap.read()
gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
_, thresh = cv2.threshold(gray, 50, 255, cv2.THRESH_BINARY)
contours, _ = cv2.findContours(thresh, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)
for contour in contours:
area = cv2.contourArea(contour)
x, y, w, h = cv2.boundingRect(contour)
# Calculate the center of the contour
M = cv2.moments(contour)
cx = int(M['m10'] / M['m00'])
cy = int(M['m01'] / M['m00'])
# Send motor control signals based on the contour position
if cx < 320:
ser.write(b'left
') # Turn left
elif cx > 320:
ser.write(b'right
') # Turn right
else:
ser.write(b'forward
') # Move forward
cv2.imshow('Frame', frame)
if cv2.waitKey(1) & 0xFF == ord('q'):
breakcap.release()
cv2.destroyAllWindows()
ser.close()
```These code examples demonstrate the versatility of the DIY 2WD Mini Round Robot Car component and its potential applications in robotics and IoT projects.
