Tutorial: How to use LSM303DLHC

The LSM303DLHC is a 3D magnetic sensor that helps determine direction and magnetic field. Useful for navigation, orientation, and magnetic field monitoring projects.

What you need

• Arduino IDE
• USB Cable
• 10kΩ Resistor
• Protoboard Paper
• Jumper Connector

Steps

1. 1. Download and install the Arduino IDE.
2. 2. Connect the LSM303DLHC to your Arduino using 6 jumpers.
3. 3. Connect the 10kΩ resistor between VCC and GND of the sensor.
4. 4. Connect VCC and GND of the sensor to your Arduino.
5. 5. Connect to your Arduino with the USB cable.
6. 6. Load the following code.
7. 7. Check magnetic data through the Arduino console.
8. 8. Refer to the datasheet for further details.

Example code

```cpp
#include <Wire.h>
#include <LSM303.h>

LSM303 lsm;

void setup() {
  Serial.begin(9600);
  if (!lsm.begin()) {
    Serial.println("LSM303 not found");
    while (1);
  }
}

void loop() {
  lsm.getM();
  Serial.print("Magnet: ");
  Serial.print(lsm.m.x); Serial.print(", ");
  Serial.print(lsm.m.y); Serial.print(", ");
  Serial.println(lsm.m.z);
  delay(250);
}
```
