The blog of the MATD3039 Advanced Musical Electronics module
Just another OurDMU site
In this week’s session we are doing our presentations about our project.
Here is my presentation
I thought that today’s lab was successful as we were able to show that we knew what we want to do for our projects and be able to explain them to others.
I think it was helpful to get any feedback/questions to think about, while we can still change our code/circuits and interfaces/case.
Now it’s just being able to build the final version of our projects.
Today’s Lab was split out over the following tasks:
What is the mechanical Workshop?
The Mechanical Workshop is a workshop where we can build/create the physical components of our projects.
Who are the contact persons?
When can you go?
Monday and Friday are the best day. But Any Day within university open times.
Where is it located?
Towards the back of the Queens Building. If you were to come in via the back entrance of Queens and continue past the stairs and lift through that door. This will lead to a corridor where you go strait ahead into the main part of the Queens Building. The mechanical workshop is down the right side corridor.
Why you should go?
It is helpful for those who need tools to build their projects.
Also if you would want to cutout materials
How are you planning to use the mechanical workshop?

Software Checklist
note that it might be an idea to work with fritzing for circuits and code but for the interface/box outer esthetics it might be a good idea to use Tinkercad to design the user interface.
But if you were creating a basic circuit and wanted to have your interface design and circuit design in one place use Tinkercad.
Some ideas of my circuit from my first instrument using Tinkercad:
TYPES OF PROJECT TIME MANAGEMENT
What is a timeline?
A timeline is a list thact can consits of dates, times and tasks that are set in cronological order (date and time order). Like a schedule or diary. Mostly used in projects and history.
What is a Gantt chart?
A Gannt Chart is a form of bar chat that shows the progress of a task or project. This is mainly used when managing projects. Gannt Charts are also used with teams as it's a way of managing who is doing what tasks and how their progress of the tasks are going. They are also mainly used when preforming more than one task at a time.
Other management ideas/methodologies for our project
So waterfall is like a timeline and Agile can be seen as a Gannt Chart.
PROJECT PLANNING SOFTWARE
What software is available to create:
Timelines
Gannt Charts
From a quick google search, you can see there are thousands and thousands of websites that will have programs and/or guides to help build either charts. From Microsoft Office (word, Powerpoint, Excel, Note, etc.) to websites like monday.com, teamwork.com.
Today’s Worksheet:
Task 1 – Make a noise using ton() and a Piezo Buzzer
For this task, we followed the instructions from the lab sheet above. We were to set up a circuit using a breadboard, Arduino (clone), 100 ohms resister, a Piezo Buzzer and some cables.
Once we have built the circuit we needed to code the Arduino to allow a sound to be created as an output.
The Code:
// A sketch to demonstrate the tone() Function
// Specifu digital pin on the arduino that the positive lead of piezo buzzer is attached.
const int piezo = 8;
void setup() {
} //close setup
void loop() {
//*Tone needs 2 arguments, but can take three.
*/
tone(piezoPin, 1000, 500);
}
Task 2 – Add a break in the loop
To create a break in the loop we added the following code after the tone() function.
delay(1000); }
Task 3 – To create a beat
we do this by adding/changing to the code we used for task 1
tone(piezoPin, 450); delay(500); noTone(piezoPin); delay(500);
Objectives
In this session, we will investigate how to add complexity to a circuit (e.g. increasing the number of sensors, complex sensors, talking to the cloud, talking to RPi) and will discuss the initial ideas of your project.
Task 1.
We are provided with the following essential sensor kit: https://www.kiwi-electronics.nl/nl/ sparkfun-essential-sensor-kit-2480.
Pick one complex sensor and explain how it works as well as what are the potential musical possibilities.
–Hall Effect Sensor–
The Hall-effect Sensor is able to distinguish between the positive and negative charge moving in the opposite direction.

Today’s worksheet
SOFTWARE/LIBRARIES
For this section of the lab we researched the types of libraries that are instilled or can be installed into the arduino software to which we can code.
To find the library, you open arduino software, then go to the sketch tab. once the drop down menu comes up then go down to include library then wait for the additional menu to come up then click on mange library.
Sketch> Include Library > Manage Library
I used the library search to find the following:
In today’s session we focused on sensors and actuators.
Today’s worksheet
For this lab session we were using a breadbord and an arduino to run a series of code to acomplish our tasks in the worksheet.
Our first task was to code the Arduino and set up a circuit that would allow us to control an LED with a push button.
I hope to grow my skills and knowlage with circuits, interfaces and sensors. Aswell as learning how to code an microcontoller.
I will mainly be using this blog as a lab book by making notes of any research and ideas for my project and assessment.
Open Source means that although the software is created/licenced under a company, this software can then be adapted to individuals need.
The software tends to be free.
Open-source software is computer software that is released under a license in which the copyright holder grants users the rights to use, study, change, and distribute the software and its source code to anyone and for any purpose. Open-source software may be developed in a collaborative public manner. Open-source software is a prominent example of open collaboration, meaning any capable user is able to participate online in development, making the number of possible contributors indefinite. The ability to examine the code facilitates public trust in the software.
https://en.wikipedia.org/wiki/Open-source_software
Integrated Development Environment, enables programmers to consolidate the different aspects of writing a computer program. IDEs increase programmer productivity by combining common activities of writing software into a single application: editing source code, building executables, and debugging.

So it is the electronic version of a of a DAW (Digital Audio Workspace).
Developing software for, or running software on, more than one type of hardware platform.
An example of this is allowing an app to work on an iPhone and Android. It just means that the software can run on different devices that are of different operating systems and has the same performance quality no matter which device a user is using.
The GNU General Public License is a series of widely used free software licenses that guarantee end-users the four freedoms to run, study, share, and modify the software.
