Creating A Piano With The Arduinolab 5aprocedure Watch The Video

Construct a circuit and program using ArduinoLab 5 to create a pentatonic micro piano. Watch the "Exploring Arduino" Chapter 5 demo video on the pentatonic piano, then replicate the circuit and code from the video and textbook chapters. Expand on this foundation by designing a circuit and Arduino program that incorporates full functionality of the pentatonic piano, uses array processing for button detection, and includes RGB LEDs to indicate notes when buttons are pressed. Record a video demonstrating the operation, include your Grantham ID in the video, and submit your .ino code file. Provide a detailed explanation of your hardware and software design process, analyze the tone() function, discuss how array processing is used with for loops, and include references in proper APA format for all sources.

The project of creating a digital piano with ArduinoLab involves integrating hardware components such as push buttons, RGB LEDs, resistors, and an Arduino microcontroller to produce a functional pentatonic scale piano. The development process begins with understanding the basic principles demonstrated in the "Exploring Arduino" Chapter 5 video, which showcases how to construct a simple micro piano. This initial step requires building the circuit on a breadboard, connecting pushbuttons to specific digital input pins, and linking RGB LEDs to output pins through appropriate resistors. The corresponding code leverages the tone() function for sound generation by manipulating these input and output components in sync.

In the software development phase, the key is to streamline button detection through array processing. By creating an array that stores the pin numbers of each button, the code simplifies the process of checking button states within a loop. This approach reduces redundancy, making the code more efficient and scalable. When a button is detected as pressed, the corresponding tone for that note is generated using tone(), and the RGB LEDs are activated to visually indicate the current note. For example, pressing a button associated with the "C" note could illuminate the yellow LED, while "D" lights up the blue LED. This visual feedback enhances user interaction and confirms the correct note is being played.

The user is encouraged to expand the basic design by incorporating colored LEDs—red, green, and blue into an RGB LED—to visually distinguish each note more vividly. To implement this, resistors are connected in series with each LED to limit current and prevent damage. The code utilizes array structures to handle each LED/note combination efficiently, and nested for loops are employed to manage multiple LEDs and buttons systematically. This demonstrates an essential application of array processing techniques, enabling dynamic and scalable management of multiple inputs and outputs.

For practical application, the project emphasizes the importance of documenting the hardware setup and software implementation through a hands-on video demonstration, in which the user’s Grantham ID is clearly visible, confirming authenticity. Screenshots of the Arduino IDE with the code running are also necessary for comprehensive assessment. The completed software code file (.ino) must be submitted alongside the demonstration video and screenshots.

In terms of explanation, the report should detail the developmental process, including how initial prototypes were refined into the final system. The use of the tone() function plays a critical role by generating specific frequencies corresponding to musical notes, with input parameters specifying the note frequency in Hertz and optional duration. It produces an audio output on a connected speaker or buzzer, enabling the synthesis of musical sounds. The implementation of array processing, particularly with for loops, allows the program to handle multiple inputs and outputs systematically, dramatically reducing code complexity and enhancing scalability—essential for expanding the project to include more notes or features.

Furthermore, the discussion extends into array processing concepts, explaining how arrays store multiple data elements that are processed in sequence or parallel, often within loops. Arrays are vital in microcontroller programming for managing sensor data, controlling multiple actuators, or handling user inputs efficiently. For example, in this project, arrays are used to hold pin numbers for buttons and LEDs, streamlining the logic needed for detecting multiple button presses and lighting corresponding LEDs, thereby demonstrating practical uses of array processing in embedded systems.

Additionally, the report explores the role of digital signal processors (DSPs). DSPs are specialized microprocessors designed for high-speed numeric calculations, crucial in applications requiring real-time data processing such as audio signal processing, speech recognition, and multimedia compression. They offer significant advantages over general-purpose microprocessors in their ability to execute complex mathematical algorithms efficiently. Leading DSP manufacturers like Texas Instruments and Analog Devices produce chips with extensive datasheets detailing their capabilities for specific applications. For instance, Texas Instruments’ TMS320 series and Analog Devices’ SHARC processors are prominent examples, each tailored for professional audio, communications, and advanced multimedia processing tasks.
