Code to show detection of distance on serial monitor
#include <NewPing.h>

NewPing sonar(10, 11, 20);

void setup() {
Serial.begin(9600);
delay(50);
// put your setup code here, to run once
}

void loop() {
Serial.print("The Distance is: ");
Serial.println(sonar.ping_cm());
delay(1000);

Connect to blender through blendix code (doesn't work properly)
#include <NewPing.h>

NewPing sonar(10, 11, 20);

float distance = 0; // Global variable to store the distance

void setup() {
Serial.begin(115200); // Initialize serial communication with a baud rate of 115200
delay(50);
}

void loop() {
distance = sonar.ping_cm(); // Measure the distance using the ultrasound sensor

// Check if an object is in front of the sensor within the range
if (distance > 0 && distance < 20) {
sendRandomValues(); // If an object is detected, send random values
}

// Add a delay of 1 second
delay(1000);
}

// Function to generate random meaningful words
String generateRandomText(int length) {
String randomText = "";

// Define an array of meaningful words
String words[] = {"apple", "banana", "cat", "dog", "elephant", "flower", "guitar", "house", "ice cream", "jungle"};
int numWords = sizeof(words) / sizeof(words[0]);

for (int i = 0; i < length; i++) {
int randomIndex = random(0, numWords); // Generate a random index to select a word from the array
String randomWord = words[randomIndex];
randomText += randomWord + " ";
}

randomText.trim(); // Remove the trailing space

Great, the sensor calculates the distance and generates values when triggered, but it doesn't speak to blender. What's next

This third code speaks to blender. The ultrasonic sensor when triggered, moves the blender model of 1m on y axis.

#include <NewPing.h>

NewPing sonar(10, 11, 20); // Ultrasonic sensor configuration

float totalDistance = 0.0; // Variable to store the total distance moved

void setup() {
Serial.begin(9600); // Initialize serial communication with a baud rate of 9600
}

// Function to send data to Blender
void sendtoBlender(float x) {
String sendData = String(x) + ",0,0," + String(x) + ",0,0," + String(x) + ",0,0;";
Serial.println(sendData); // Print the combined data to the serial monitor for communication with Blender
}

// Function to generate random meaningful words
String generateRandomText(int length) {
String randomText = "";

// Define an array of meaningful words
String words[] = {"apple", "banana", "cat", "dog", "elephant", "flower", "guitar", "house", "ice cream", "jungle"};
int numWords = sizeof(words) / sizeof(words[0]);

for (int i = 0; i < length; i++) {
int randomIndex = random(0, numWords); // Generate a random index to select a word from the array
String randomWord = words[randomIndex];
randomText += randomWord + " ";
}

randomText.trim(); // Remove the trailing space

return randomText;
}

// Function to generate random axis values
String generateRandomAxis() {
String axis = "";
float x = random(-10, 10); // Generate a random floating-point number between -10 and 10 for x
float y = random(-10, 10); // Generate a random floating-point number between -10 and 10 for y
float z = random(-10, 10); // Generate a random floating-point number between -10 and 10 for z

axis = String(x) + "," + String(y) + "," + String(z); // Concatenate the generated axis values into a single string

return axis;
}

// Function to generate and send fixed data to Blender
void generateAndSendData() {
// Increment the total distance by 1 meter
totalDistance += 1.0;

// Generate the data in the correct format for Blender
sendtoBlender(totalDistance);
}

void loop() {
// Measure the distance using the ultrasonic sensor
float distance = sonar.ping_cm();

// Check if an object is detected within the specified distance range (adjust as needed)
if (distance > 0 && distance < 20) {
// Call the function to generate and send data when an object is detected
generateAndSendData();
delay(2000); // Wait for 2 seconds to avoid rapid multiple triggers (adjust as needed)
}
}
