How to Connect LDJ-200 to Arduino
The LDJ-200 sensore di distanza laser is compatible with Arduino using TTL UART.
Wiring Tips:
- Use level shifter if needed (Arduino 5V <-> Sensor 3.3V TTL)
- Connect to external power supply (12V recommended)
- Share common ground with Arduino
Sample Arduino Logic (Pseudo-Code):
void loop() {
if (Serial1.available()) {
float distance = readLaserSensor(); // Your parsing function
Serial.print("Distance: ");
Serial.print(distance);
Serial.println(" mm");
}
}
