#Ultrasonic Sensor Arduino Project

[nilima-2003]

SERVO DISTANCE INDICATOR USING ARDUINO UNO

INTRODUCTION

Distance measurement is a fundamental concept in various fields, including robotics, automation, and security systems. One common and efficient way to by emitting sound waves and calculating the time it takes for the waves to reflect back from an object, allowing accurate measurement of distance without physical contact.

In this project, we will use an HC-SR04 Ultrasonic Sensor in conjunction with an Arduino microcontroller to measure the distance between the sensor and an object. The sensor emits ultrasonic waves and measures the time it takes for the waves to return after reflecting off the object. By using the speed of sound and the time measured, the distance is calculated. This simple yet powerful setup can be applied in a variety of real-world applications such as obstacle detection in robots, parking assistance systems, and automatic door operations.

WORKING PRINCIPLE

1. Servo Movement: The servo motor rotates to different angles (0° to 180°). The ultrasonic sensor is mounted on top of the servo and moves with it.

2. Distance Measurement: At each position, the ultrasonic sensor sends out an ultrasonic pulse and waits for the echo to return after hitting an object. The Arduino records the time taken for the echo to return.

3. Distance Calculation: The Arduino calculates the distance to the object based on the time recorded and the speed of sound (0.0343 cm/µs).

4. Servo as Indicator: The servo motor's position provides a physical indication of the direction of the detected object. As the servo moves across a range of Image map out objects in different directions based on distance.

5. Visual Output: The Arduino can also send the distance and angle data to the serial monitor, creating a real-time visual representation of the detected object positions.

APPLICATIONS

1. Autonomous Robots and Vehicles

2. Radar Systems

3. Parking Assistance

4. Security Systems

6. Warehouse Management and Automation

7. Industrial Automation

8. Robotic Arm Guidance

How'd the Arduino build go? I couldn't finish the stream 😭. Also, I couldn't tell but how big was the joystick? 🕹️

the arduino build was fun! i managed to get the LEDs to work but i've forgotten how to configure a breadboard...

i fiddled with some equipment yesterday!

a water level sensor, which was easy to setup, then an ultrasonic sensor which i think might be faulty because it always returned the same values to me. finally, i tried the humidity and temp sensors and they worked fine! it's been really fun working with the arduino so far :3 i'm trying to build a plant monitor as a first project (something that's been done a thousand times already!) so i'm excited!

i'll reblog this with a picture of the joystick once i get to it..... gimme a min

Spring Break – BreakCore Music Player

Final Project

For my final project in physical computing, I designed and built a digital musical instrument that I call the Spring Break – BreakCore Music Player. Drawing inspiration from the New Interfaces for Musical Expression (NIME) movement, this instrument transforms hand gestures into musical actions, allowing me to perform and manipulate breakcore-style audio using two ultrasonic distance sensors connected to an Arduino and mapped into Max MSP. It’s a controller, a performance tool, and a kind of interactive sculpture all in one—and it really made me feel like I was DJing a rave set with my hands.

The original concept came together as I experimented with the HC-SR04 distance sensors. I had initially planned to use motion sensors, but they proved too difficult to wire. After talking with someone more experienced, I pivoted to ultrasonic sensors since they offer similar spatial sensing but with more reliable outputs. Once I got one sensor working, I saw how smoothly it could translate distance into digital signals, so I added a second. This two-sensor setup let me build a kind of “on/off” control system, where each hand movement could start or stop specific layers of music.

The physical design of the instrument was simple but meaningful. I laser cut a small enclosure using MakerCase and acrylic in the Spelman Innovation Lab, and decorated it with a guitar-shaped design on the front panel to visually signal its purpose as a musical object. Inside the box, I mounted the Arduino and wired both sensors to a single breadboard—something I hadn’t done before, but it worked flawlessly on the first try. The sensors were positioned facing upward so I could hover my hands over them during the performance.

Left: Arduino Code for first sample, Right: Testing first sample

The Arduino code handled the distance calculations and serial output. Each sensor was triggered in the loop, calculating the distance in centimeters and printing both values as a single line of data. Here's the exact code I used:

const int trigPins[2] = {9, 11};

const int echoPins[2] = {10, 12};

float distances[2];

long duration;

void setup() {

Serial.begin(9600);

for (int i = 0; i < 2; i++) {

pinMode(trigPins[i], OUTPUT);

pinMode(echoPins[i], INPUT);

}

}

void loop() {

for (int i = 0; i < 2; i++) {

// Trigger pulse

digitalWrite(trigPins[i], LOW);

delayMicroseconds(2);

digitalWrite(trigPins[i], HIGH);

delayMicroseconds(10);

digitalWrite(trigPins[i], LOW);

// Read pulse

duration = pulseIn(echoPins[i], HIGH, 30000); // timeout safety

distances[i] = (duration * 0.0343) / 2;

// If no signal, set to 0

if (duration == 0) distances[i] = 0;

// Print to serial

Serial.print(distances[i]);

Serial.print(" ");

}

Serial.println(); // New line

delay(100);

}

In Max MSP, I created a patch that received the serial data from the Arduino, unpacked it, and used simple conditional logic to check whether the hand was within a certain threshold distance—specifically 20 centimeters. If so, it sent a bang that triggered a set of audio samples. Each sensor was mapped to a different set of three layered breakcore audio loops. Here’s the final version of the patch:

The left and right sides of the patch represent each of the sensors. When a hand is detected within range, it activates all three samples on that side, creating a stacked, textured sound. I didn’t map pitch or volume directly, but the threshold-based triggering gave me solid, real-time control over the performance. The layering of audio and the fast, cut-up loops created that signature breakcore energy I was going for.

When it came time to compose a piece, I built my sound palette from breakcore-inspired loops and samples I either made or found online. The genre naturally lends itself to this kind of chaotic, reactive interaction. Once I tested the first drum loop with my hand and saw it activate in sync with my movement, I knew exactly what direction to go. My final piece was more of an improvised jam session than a strict composition, but that made it feel alive—and I genuinely felt like I was DJing with air gestures.

This project wasn’t easy. Learning Max MSP from scratch was a major challenge. The interface is not beginner-friendly, and figuring out how to parse serial data, unpack values, and link it to audio playback took a lot of trial and error. I also ran into a brief issue where one of my sensors wasn’t showing up in the serial monitor, which I eventually solved by testing it in a separate sketch and reconnecting the wiring. Another challenge was figuring out how to keep the whole build compact—I’d used two breadboards in my midterm, but I managed to wire both sensors on one board for this project, which helped with space and structure.

If I had more time, I’d love to build on this project by introducing more nuanced sound control. Maybe mapping pitch to distance, adding a third sensor for tempo control, or even building a visual interface with responsive lights or projections. I can definitely imagine this evolving into a fully-fledged digital instrument or live performance tool.

More than anything, this project taught me that I can make music with my hands—literally. I now understand how to translate gesture into sound, how to route sensor data into an audio environment like Max MSP, and how to create systems that feel playful and expressive. I walked into this project nervous about how much I didn’t know, and I came out of it with a finished, functional instrument that let me perform a genre I love. That’s something I’ll carry with me well beyond this class.

S.O to the Spelman Innovation Lab, the IL staff and Professor Holmes- I couldn’t have don’t this without you!
