Components Required:
- Arduino board (e.g., Arduino Uno)
- LIDAR sensor (e.g., VL53L0X)
- LED array (e.g., 8x8 LED matrix)
- Connecting wires
Step 1: Setting Up the Libraries and Hardware
To get started, include the necessary libraries for the LIDAR sensor, LED array, and I2C communication. Ensure that the LIDAR sensor and LED array are properly connected to your Arduino.
```cpp
#include
#include
#include
#include
VL53L0X sensor;
#define MAX_DISTANCE 200 // Maximum detection distance in millimeters
Adafruit_8x8matrix matrix = Adafruit_8x8matrix();
```
Step 2: Initializing the Components
In the `setup()` function, initialize the LIDAR sensor and the LED array. Additionally, verify if the LIDAR sensor is functioning correctly.
```cpp
void setup() {
Serial.begin(9600);
Wire.begin();
sensor.init();
sensor.setTimeout(500);
if (!sensor.init()) {
Serial.println("Failed to initialize LIDAR sensor!");
while (1);
}
matrix.begin(0x70); // Use the correct I2C address for your LED matrix
matrix.clear(); // Clear any existing content on the LED array
matrix.writeDisplay(); // Update the LED display
}
```
Step 3: Main Loop for Scanning and Mapping
```cpp
void loop() {
matrix.clear();
int distance = sensor.readRangeSingleMillimeters();
int brightness = map(distance, 0, MAX_DISTANCE, 0, 15);
int ledX = constrain(map(distance, 0, MAX_DISTANCE, 0, 7), 0, 7);
int ledY = 7; // You may need to adjust this based on your LED matrix orientation
matrix.drawPixel(ledX, ledY, brightness);
matrix.writeDisplay();
Serial.print("Distance: ");
Serial.print(distance);
Serial.print(" mm | LED Position: (");
Serial.print(ledX);
Serial.print(", ");
Serial.print(ledY);
Serial.println(")");
delay(100);
}
```
Conclusion:
You have successfully built a remarkable program that uses a LIDAR scanner on an Arduino board to map the position of intruders on an LED array. This interactive project beautifully combines the capabilities of the LIDAR sensor and LED matrix to visualize the proximity of objects surrounding the sensor.
