Hands on Music


First of all we must know that the glove is a musical instrument. It is composed of a glove to which are applied flexibility sensors that are inserted into a circuit among which elements we find ARDUINO and a musical shield. The objective of the instrument is to emit pleasant sounds through the flexion of the fingers in a simple and natural way.


1.1 How the glove works:
In order to make the glove, it is necessary to have a flexibility sensor for each finger, fixed on its back in such a way that it adheres and follows it during the flexion which will then lead to the activation of the program to emit the respective note. Each sensor is connected through cables to the breadboard and then to ARDUINO.

1.2 Programming:
A premise to make is that for our program we have taken advantage of a previously written code that can be used to command the musical extension (https://dlnmh9ip6v2uc.cloudfront.net/assets/4/9/1/2/0/512276a2ce395f9712000000.zip).
The logic of the program is very simple: when the input signal, received by the arduino board through the analog port, exceeds a set value the noteOn function allows the production of the note.
The notes to be used can be inserted in the noteValue array, while the chosen instrument can be associated to the instrument variable. (It is good to specify that the value of these variables must be integer. The note-number correspondence is easily acquired from the web).


2.1 Glove:
To build the structure we have taken into account some points that must be respected in order for the whole apparatus to work properly, namely:
the structure must be easily wearable;
the structure must be autonomous and not tied to non-portable instruments or that would limit its movement;
the cables that make up the structure must be fixed or tied between them in such a way as not to hinder movement;;
the structure must be adjustable and adaptable from person to person;
As for the actual assembly part, the steps to complete it are few and simple. First of all it is necessary to create on the back of all the fingers a sort of “hood” of cloth inside which the flexibility sensors are positioned. Once assembled everything should be fixed to the glove with needle, thread and tape to protect the connection between the cables and sensors. After that we have to braid the wires so that they all converge on the mini-breadboard. After that we must close the circuit by connecting mini-breadboard to arduino.

2.2 Electronic part:
Our tool is based on a simple circuit as shown in the image below:

The positive cable of each flex-sensor must be connected directly to the 5V port of Arduino while the negative must be led to both the pin corresponding to the sensor and to ground.


The project was initially born as a proposal to have fun with music in a different way. During the construction we realized the potential that such an instrument could have. Talking with competent people we have ascertained the ability in the medical field, with regard to psychological rehabilitation. We then set out to improve the support and we are still working.
