• • Raspberry Pi (2 or 3) with SD card

  • 8 HC-SR04 ultrasonic sensors

  • Octasonic Breakout Board

  • Bi-Directional Logic Level Converter

  • 32 x 12" Female-Female Jumper Wires for connecting the ultrasonic sensors

  • 13 x 6" Female-Female Jumper Wires for connecting the Raspberry Pi, Octasonic, and Logic Level Converter

  • Suitable power supply for the Raspberry Pi

  • PC speakers or similar

  • Adafruit STL2561 Lux Sensor

  • Card Board​​

 

Step 2: Connect the Ultrasonic Sensors to the Octasonic Board​

​

Step 3: Connect the Logic Level Converter to the Octasonic Board

​

• • 5V to HV

  • SCK to HV4

  • MISO to HV3

  • MOSI to HV2

  • SS to HV1

  • GND to GND

Step 4: Connect the Logic Level Converter to the Raspberry Pi

​

• • 3.3V to LV

  • GPIO11 (SPI_SCLK) to LV4

  • GPIO09 (SPI_MISO) to LV3

  • GPIO10 (SPI_MOSI) to LV2

  • GPIO08 (SPI_CE0_N) SS to LV1

  • GND to GND

Step 5: Connect Raspberry Pi 5V to Octasonic 5V​

• To power the Octasonic board

  • Connect one of the the Raspberry Pi 5V pins to the 5V pin on the Octasonic AVR header----the bottom left pin in the 2 x 3 block on the top right of the board.​

​

Step 6: Install Software​

• On Raspberry Pi, install the following

  • FluidSynth​

  • Rust Programming Language

• Download our source code in GitHub

  • Ultrasonic Light Piano Repository​

​​

Step 7: Make Music!

• Unzip the source code, then navigate into the folder

• Build the code using command:   cargo build --release 

• Run the code using command:   ./run.sh 

• Connect speakers to the 3.5mm audio jack on the Raspberry Pi and you should hear music as you move your hands over the sensors.

Assembling Light Sensor

​Step 1: Connect the light sensor to Arduino board (here we are using Teensy 3.1)

• Use the example code from TSL2561 Arduino Library provided by Adafruit : https://github.com/adafruit/TSL2561-Arduino-Library

• Modify the code to print only the luminosity of visible light (the "X" variable)

Step 2: Connect the Arduino board to Raspberry Pi using USB cord

• Use Rust SerialPort library to read serial port: https://crates.io/crates/serialport

• Modify UltrasonicPiPiano code to use luminosity data to update instrument

​

Box Assembly

• Purchase bendable cardboard

• Cut out the cardboard, which has four pieces in total.

• Assemble the pieces together, arrange the Raspberry Pi, breadboard, and wires within the box, and secure the box with hot glue or tape.
