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!

A Passive Infrared (PIR) sensor detects infrared radiation emitted by objects, especially humans. The sensor outputs a digital signal (HIGH or LOW) depending on whether it senses motion. It’s called "passive" because it doesn’t emit any energy; it just senses the infrared rays from the surrounding environment.

How PIR Sensors Work:

The PIR sensor consists of two key components:

Pyroelectric sensor: Detects infrared radiation.

Fresnel lens: Focuses the IR signals on the pyroelectric sensor. When a warm body (like a human) moves across the sensor’s field of view, the infrared radiation changes, and the sensor detects this change, sending a HIGH signal.

Components Required:

Arduino (e.g., Uno, Nano, or Mega)

PIR Sensor

Jumper Wires

Breadboard

LED (for visual feedback)

220Ω Resistor (for the LED)

Circuit Diagram:

sql

Copy code

[Insert a simple diagram showing the connections between Arduino, PIR sensor, and LED]

Connections:

Connect the VCC pin of the PIR sensor to the 5V pin of the Arduino.

Connect the GND pin of the PIR sensor to GND on the Arduino.

Connect the OUT pin of the PIR sensor to digital pin D2 on the Arduino.

Optionally, connect an LED to pin D13 (with a 220Ω resistor for safety) to provide a visual indicator when motion is detected.

Arduino Code:

Now that you have connected the PIR sensor, let’s upload some code to the Arduino. The following code reads the PIR sensor’s output and lights up an LED when motion is detected.

cpp

Copy code

// PIR Sensor Pin Definitions

int pirPin = 2; // Connect the PIR sensor output pin to D2

int ledPin = 13; // LED pin (optional for motion indication)

void setup() {

pinMode(pirPin, INPUT); // PIR sensor as input

pinMode(ledPin, OUTPUT); // LED as output (optional)

Serial.begin(9600); // Initialize Serial Monitor

}

void loop() {

int pirState = digitalRead(pirPin); // Read PIR sensor's output

if (pirState == HIGH) { // Motion detected

digitalWrite(ledPin, HIGH); // Turn on LED

Serial.println("Motion detected!");

} else { // No motion

digitalWrite(ledPin, LOW); // Turn off LED

Serial.println("No motion");

}

delay(1000); // 1 second delay between readings

}

Explaining the Code:

pinMode(): Defines whether the pin is an input or output.

digitalRead(): Reads the PIR sensor output (HIGH or LOW).

digitalWrite(): Controls the LED based on sensor output.

Serial.begin(): Starts serial communication for debugging.

When the PIR sensor detects motion, the pirState variable becomes HIGH, turning on the LED and printing "Motion detected!" to the serial monitor.

Testing the Setup:

Connect your Arduino to your computer and upload the code.

Open the Serial Monitor from the Arduino IDE (Tools > Serial Monitor).

Wave your hand in front of the PIR sensor to test if it detects motion.

If motion is detected, the LED will light up and the message will appear in the Serial Monitor.

Adjusting the PIR Sensor Sensitivity:

Most PIR sensors come with two potentiometers for adjusting sensitivity and delay time. Sensitivity determines the range of detection, and delay time sets how long the output remains HIGH after motion is detected.

Sensitivity Potentiometer: Rotate to increase or decrease detection range.

Delay Time Potentiometer: Adjust how long the PIR sensor output stays HIGH after motion.

Applications of PIR Sensors:

Home Security Systems: Detect intruders and trigger alarms or cameras.

Smart Lighting: Automatically turn lights on when someone enters a room.

Automatic Door Openers: Use PIR sensors to detect approaching people and open doors.

Energy-Efficient Devices: Turn off appliances or lights when no motion is detected, reducing power consumption.

Troubleshooting:

False Positives: If the sensor triggers without motion, reduce the sensitivity or place the sensor in a more controlled environment.

No Motion Detection: Double-check the wiring and ensure that the sensor is properly powered and connected to the correct pins.

Conclusion:

You have successfully interfaced a PIR sensor with an Arduino to create a basic motion detection system. This simple project can be expanded into various applications like security alarms, smart home systems, and automation projects.

By following this blog, beginners will get a solid foundation in interfacing a PIR sensor with an Arduino. Advanced users can add features like buzzer alarms, wireless communication, or integra

After Exam

We started testing connecting it to a microcontroller, we already coded programs for sensing vibration or getting input and giving output from the shock sensor to the serial monitor of the Arduino IDE. We had results and every time it is being triggered by vibration it reaches to zero (0). If not, the value is above 1000. 

Next we tried the Laser Sensor. We also pre-programmed how we would get input and output from the Light Dependent Resistor (LDR) every time the laser is on or off. Laser is a very concentrated type of light so the values were really great compared to ordinary or the natural light. When the laser is being directed to the LDR it gives value about 1000 also and when it is off there is about 500 or below and when covered we get 0-20 values printed in the serial monitor of the Arduino IDE.

We wanted to try the GSM module next but we had problems with it since it’s our first time trying to configure it. But rest assured we will get this. By now we are still looking for mirrors that would fit in the car and would reflect great for the laser module.

Today is the week for the posting of midterm grades and our hearts cannot stop beating fast every time we open our sis accounts to check our grades. But it never stops us in making our project.

Personal Project 8 - All Components Together + Serial

Components

1x Arduino UNO w/ USB Cable 1x Breadboard 1x Momentary Switch, Red 1x Potentiometer, Dial 1x Liquid Crystal Display 1x 10k Ohm resistor M to M wires to connect components

Description - Display, Button, Dial

In conjunction, each of the components work in a similar function as they have done in previous experiments. The LCD and momentary switch are set up in the same way as the previous post, the button sending input to pin D10, and the LCD being wired to fix the issue posed in Post 7, avoiding the PWM pin and using pin 12 instead.

Description - Application, Serial Communication

The application is unfinished for this version, simply due to time constraints. After carrying out research on using Arduinos as a HID, the main intent of this project, I discovered a library for Arduino that enables a board like an UNO to replicate a HID, as they are not natively able to do so. This requires burning a new bootloader onto the Arduino's secondary chip, which has a risk of bricking the chip entirely, which disable USB data transfer and significantly reduce the boards functionality. I discovered this risk quite late into development, and had to change course to use serial data communications to send commands to the windows forms app instead.

This meant that I had to change the way the application worked significantly, as it now had to handle serial communication as well as sending keystrokes. Both of these functions would be complex additions, on top of having to change how the shortcut data would stored. Initially the idea was to have the data stored in a header file, which could be updated and reuploaded to the board via the app. This changed to the data being stored on the users PC and the serial port communication handling the commands from the Arduino within the application.

Evaluation

Overall, I'm quite happy with the physical creation side of this project, however the application has left a lot to be desired, as it is mostly unfinished; more of a collection of concepts and ideas that would work, but have not be executed upon. The physical side has allowed me to expand my knowledge of Arduino programming, electronics, and serial based communication, while the application side has given me the opportunity to experiment with a new tool, which is something I may experiment with in the future.

I believe that there would be a market for a product like this, a more complex version of a stream deck. The surface dial is a similar product/accessory to Microsoft's surface series computer and has a significant number of functions.

To improve upon the design, a better physical form factor would be needed, something similar to a stream deck in format, as well as an actual method of programming it.

Assignment 3 Iteration 13

In this iteration I’ve done some cleaning of the code and reorganising different components within it. I fixed the start state with the blinking LCD which was not working exactly as I wanted it to before. I’ve added the feature that you can go back from finalisation of your name to entering it, as well as being able to go back from the balance stage to the starting stage. I’ve also began to lay out the foundations for the connectivity with processing, testing how to write the name and the time of the player to the Serial Monitor. I’ve also thought of adding a feature that only allows you to enter your name to submit your time to the leaderboard if processing is connected, as there is no point entering your name if you cannot submit it to the leaderboard. This will be done by sending a certain byte that when received by processing, it will respond by sending a certain byte as well. If Arduino ever receives this byte that means that Arduino is connected and thus, we can allow the player to enter their name.

Lego Port Devices Driver

When you plug the device into your USB, Windows will look for the associated driver, if it cannot find this driver then you will be prompted to insert the driver disc that came with your device. Common USB Device errors are ‘usb port not working‘, ‘device descriptor request failed error’ or ‘bugcodeusbdriver’ issues. See the The lego-port Subsystem for information on how to manually load the correct driver. (1, 2, 3) The automatic detection algorithm detects this sensor as an I2C sensor and the port is automatically put into I2C mode. Find the Bossa Program Port device. Right click the device and select 'Uninstall'. Disconnect the NXT brick from the computer, wait a few seconds. Reconnect the NXT brick to the computer and wait a minute or two for the system to find and install the correct NXT firmware update driver for it.

Intro

The LEGO Dimensions game makesuse of NFC technology to allow some interaction between physical LEGO creations(characters, vehicles and gadgets) and the videogame.

The LEGO Toy Pad is in fact just a custom USB triple NFC reader that can readNFC tags (not only the LEGO Toy Tags but also several other tags including thoseused in other games like Disney Infinity) and change the color of the RGB lightassociated to each reader.

Credits

Since the beginning of 2015 several people have been reverse engineering theLEGO Toy Pad.This tutorial is strongly based on @woodenphonework available at GitHub.

Requirements

You will need:

a proper LEGO Dimensions Toy Pad

a Mindstorms EV3

an available USB port

python and pysub

udev rule

Several people reported a difference between PS3/PS4/Wii devices and Xbox sothis tutorial most probably will not work with the Xbox type.

You don’t really need a Mindstorms EV3 as this tutorial can be used on almost anyrecent linux system (like my Ubuntu laptop or my Raspberry Pi). If using ev3dev,just be sure to use a recent version - this tutorial was tested with kernel4.4.15-13-ev3dev-ev3.

Of course, you need an available USB port so if you’re already using the MindstormsEV3 with an USB Wi-Fi dongle you will also need an USB Hub.

After you connect the LEGO Toy Pad it should be recognized as an HID device:

You can also check with lsusb:

You also need python and pyusb. Most Linux distributions alreadyinclude python as default so you probably only need to install the pyusb librarywith:

To allow python script to access USB without running with root privileges we needto add an udev rule:

with the following rule inside:

then unplug and replug the LEGO Toy Pad again. Pcp drivers to avoid admissions.

The USB device does not support the operation with the Windows standard. For most devices, the Ports device setup class and the Serial function driver provide the functionality required to operate serial ports and COM ports. To install serial ports and COM ports using these system-supplied components, do the following.

Changing pad colors

In the above script we’ve seen that all commands sent to the LEGO Toy Pad havethe same size: 32 bytes.

The first bytes define the command, some other bytes the arguments and theremaining bytes are just to assure proper communication (checksum).

I’ll show just how to change the color of each pad but there are some othercommands available (switch on/off, fade, flash…). You can see these commandsin @woodenphone’s lego_dimensions_gateway.py script.

Reading tags

Whenever a tag is inserted or removed the LEGO Toy Pad sends a 32-byte messagestarting with 0x56. The message also contains:

the number of the pad affected

the UID of the tag inserted or removed

the action itself (tag was inserted or removed)

So if we already know the UID of a tag we can track it with the LEGO Toy Pad (Iuse my Android phone to read my tags but we can also use the LEGO Toy Pad).For the next script we’ll track Darth Vader from Disney Infinity 3.0 (a MifareClassic Mini tag) but we can track several types of NFC tags - LEGO Toy Tags areMifare Ultralight C (also known as NTAG213) and Nintendo amiibo are also MifareUltralight (but not C, so NTAG215).

Action actina costa e series driver download for windows 10 windows 7. The script also tracks unknown UIDs. So:

if it recognizes Darth Vader, it turns the corresponding pad RED;

if it doesn’t recognize the tag, it turns the pad GREEN;

whenever a tag is removed it turns the pad OFF:

Lego Port Devices Driver Updater

In device manager the brick had a device description Bossa Program Port. It should be LEGO MINDSTORMS NXT.

Uninstalling the driver and reinstalling it still shows Bossa Program Port.

So I found the hardware ID of the Bossa Program Port from device manager (USBVID_03EB&PID_6124).

Then I went to the c:Windowsinf directory and searched for that ID.

That ID appeared in two INF files oem11.inf and oem42.inf.

oem11.inf has the device description 'LEGO MINDSTORMS NXT Firmware Update Mode' and oem42.inf has the description 'Bossa Program Port'.

So that's why it installed the wrong driver.

Knowing that, I renamed oem42.inf to oem42.inf.bak and then uninstalled 'Bossa Program Port' from device manager and repluged the NXT

It's actually the Arduino IDE itself.. Their Arduino Due uses a Atmel 32-bit processor, similar to the NXT, and the same controller (ATMEGA328P)

Update Log 8/4/21

This week I worked on fixing small issues in Unreal such as the delay and smoothing out the rotation of the camera. I was able to completely resolve the delay issue, after looking over the delays in the blueprint and in the arduino code I realized that I had done some very basic math wrong which has now been fixed. The camera does now rotate on both axes and the rotation is mostly correct but I have noticed some slight errors with it. I have a plan on how to fix this and will be implementing it later today. Lastly I began and finished the Unity demo for the Kino Wheels. I wrote a script that will connect to the arduino and the camera rotates very smoothly. One little hangup that I have just thought about while writing this post if that the way the serial port is opened in the script may need to be reworked slightly, as after watching several tutorials I noticed that arduinos can connect to different COM ports. Currently I am connecting to COM4 which is hard coded in the script, I will be adjusting that so that it can be changed easily by anyone using the script in the future.

Over the next week I plan to finish cleaning up any little bugs that I notice and testing the Kino Wheels as much as possible. Looking at the current state of things I would say that I would say that everything should be done by next week at the latest

Assignment 3

Proximity Sensor Research

The sensor that I picked for this week was a PIR Motion Sensor!

It allows you to sense motion, (most of the time it is used to detect whether a human has moved in or out of the sensor’s range. Advantages include them being small, inexpensive, low-power, easy to use and not wearing out. 

They are commonly found in gadgets and appliances used in homes or businesses. 

How it works: Passive infrared (PIR) sensors use a pair of pyroelectric sensors to detect heat energy in the surrounding environment. These two sensors sit beside each other, and when the signal differential between the two sensors changes (if a person enters the room, for example), the sensor will engage. 

Brainstorm of ideas! (PIR motion sensor)

1) LED light motion-based color fade change: In parties for example, LED lights are often used to bring life to the party. It would be cool if LEDs wrapped around pillars, plants, furniture etc, could change the color combinations depending on a person walking past the object. 

2) Burglar alarm system: I feel like this one makes sense and is pretty straight forward

PIR motion sensor in my project

I thought this would be an awesome thing to implement in to my last project which I really want to expand on. If I were to turn this in to a larger scale koi pond art installation, it would be cool to have the koi fish move depending on how close people are to the installation (eg. they could swim faster as they get closer to the sensor.) 

I really wanted to try this out, however my sensor arrived late and I wasn’t able to come to the IMA building to test it out. However, I will come in some time this week to physically try it out. 

For now, I did a simulation with some code I found during my research (PIR motion sensor + servo motor!)

When motion is detected, the servo turns 90 degrees, and if it isn’t, it rotates back to 0 degrees. 

Code: 

/* * Created by ArduinoGetStarted.com * * This example code is in the public domain * * Tutorial page: https://arduinogetstarted.com/tutorials/arduino-motion-sensor-servo-motor */ 

#include <Servo.h> // constants won't change const int MOTION_SENSOR_PIN = 7; // Arduino pin connected to motion sensor's pin const int SERVO_PIN         = 9; // Arduino pin connected to servo motor's pin Servo servo; // create servo object to control a servo // variables will change: int angle = 0;          // the current angle of servo motor int lastMotionState;    // the previous state of motion sensor int currentMotionState; // the current state of motion sensor void setup() {  Serial.begin(9600);                // initialize serial  pinMode(MOTION_SENSOR_PIN, INPUT); // set arduino pin to input mode  servo.attach(SERVO_PIN);           // attaches the servo on pin 9 to the servo object  servo.write(angle);  currentMotionState = digitalRead(MOTION_SENSOR_PIN); } void loop() {  lastMotionState    = currentMotionState;             // save the last state  currentMotionState = digitalRead(MOTION_SENSOR_PIN); // read new state  if (currentMotionState == LOW && lastMotionState == HIGH) { // pin state change: LOW -> HIGH    Serial.println("Motion detected!");    servo.write(90);  }  else  if (currentMotionState == HIGH && lastMotionState == LOW) { // pin state change: HIGH -> LOW    Serial.println("Motion stopped!");    servo.write(0);  } }

I thought this was a cool start. I want to actually physically try it and maybe get it to rotate back and forth (looped) automatically when motion is detected.

A couple of Mac users have said “the driver crashes my mac Sierra how do I uninstall”.

Firstly regards the crash make sure you installed the 1.3 version of the driver, not the old one. You could download it directly from the Manufacturers Website in case they have issued an update since I wrote this page.

Secondly a quick google search reveals that this is how you uninstall:

Open a terminal and type: cd /Library/Extensions/

Verify that the .kext file is present: ls | grep usbserial.kext

Output should be: usbserial.kext

Then type: sudo rm -R usbserial.kext

Verify that the .kext file has been removed: ls | grep usbserial.kext

Output should be empty.

After you should remove the files stored in receipts folder: cd /private/var/db/receipts/

Find the enties: ls | grep usbserial*

Output should be: codebender.cc.ch34xinstaller.usbserial.pkg.bom codebender.cc.ch34xinstaller.usbserial.pkg.plist

Remove each one of the files of the above list: sudo rm -r filename`

Just a quick walk through how to use the SD card module with Arduino. It is the same for Micro SD card modules. The Arduino official site provide a library for this purpose, and I will describe how I used this library and explain what each function does.

The SD card module communicates with the Arduino over the serial peripheral interface (SPI) communication protocol. It can be simply connected to the Arduino’s hardware SPI pins. LCD with I2C Module to the Arduino As the name implies, the LCD module communicates with Arduino through I2C communication. After a week of research, brainstorming and studying we ended up making, the SD-CARD (social distancing icard). The SD-CARD consists of an Arduino Nano which is connected with a buzzer, an ultrasonic sensor and 2 LEDs. The ultrasonic sensor calculates the distance between the person wearing it and people near him/her.

Buy the Arduino from: Banggood | Amazon

Buy SD Card Module from: Amazon | Banggood

I have not tested this library with all the SD card modules, but I think it should work for majority of them, unless you are told by the seller that you should use a different library.

The Library uses standard SPI interface for communication, which hasSPI buses, MISO, MOSI, SCK (CLK) and a chip select signal pin, CS.

(pic)

** MOSI – pin 11 ** MISO – pin 12 ** SCK (CLK) – pin 13 ** CS – pin 4

The default Arduino library for SD card is huge! With the example read/write sketch, when compiled it’s 13690 Bytes which is half of the available flash space on an Arduino pro mini!

So if you are tight in sketch space, it’s a good idea to find a smaller library. Depends on the SD cards you have and the format you want to use, you have these options.

FAT32 Format (larger than 2GB)

Adafruit SD (almost the same as Arduino SD, except a few optimization on SRAM memory)

FAT16 Format (smaller than 2GB)

I haven’t tested all of these libraries, so do your research and test them before using it. Here I will show you how to use the Arduino SD library.

The SD library comes with the Arduino IDE, so you don’t need to download it. It needs to be include at the beginning of the sketch.

Including `SD.h` automatically creates a global “SD” object which can be interacted within a similar manner to other standard global objects like “Serial”.

Read from SD card

First you need top open the file first.

It will return false if it fails to open the file, so check dataFile before using it. The “read” function reads the file line by line, so you will have to use a while loop, until it fail to reach the end of the file. Now you can write to the file using this.

Note that you need to close the file after finished reading it. Also, you can only open one file at a time, if you want to read the next file, you need to close the current file first.

Write to SD card

First you need to open the file you want to write to with “FILE_WRITE” parameter.

The “open” function takes two parameters, file location and mode (only required for “Write”, if missing by default it opens the file in Read-Only mode). It will return false if it fails to open the file, so check dataFile before using it. Now you can write to the file using this.

Note that you need to close the file after writing to it. Also, you can only open one file at a time, if you want to open the next file, you need to close the current file first.

Check if a File Exists

Create a Text File on SD Card

There isn’t a function for this purposes, but you can open a file with “FILE_WRITE” mode to create a file, if this file doesn’t exist.

Delete a File on SD card

List All the files on SD card

There isn’t a function for this in the library, but we can create a custom function to achieve this purpose. This function is from the example sketch in the Library. It prints the file directory to serial monitor.
