🛠️ Wiring the Laser Distance Measuring Module
Connecting the LDJ-200 laser sensor to your Arduino is straightforward. It supports UART and I²C interfaces, allowing flexible integration with المتحكمات الدقيقة. Ensure proper wiring for:
- VCC → 5 فولت
- GND → GND
- TX/RX → Arduino RX/TX (if using UART)
🧠 Arduino Code Example
Here’s a basic sketch to read distance from the LDJ-200 using UART:
#include <SoftwareSerial.h>
SoftwareSerial laserSerial(10, 11); // RX, TX
باطلة الإعداد() {
يبدأ المسلسل(9600);
laserSerial.begin(9600);
}
حلقة باطلة() {
if (laserSerial.available()) {
int distance = laserSerial.parseInt();
Serial.print("المسافة: ");
Serial.print(distance);
Serial.println(" mm");
}
delay(200);
}
