Components Required:

1. Arduino board (e.g., Arduino Uno)
2. LIDAR sensor (e.g., VL53L0X)
3. LED array (e.g., 8x8 LED matrix)
4. 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); } ```
