Miguel

The project was developed with the aim of providing meaningful support to individuals with hearing impairments within the home environment. Miguel is a system designed to notify the user, through a visual signal, of the completion of an appliance's operating cycle - typically indicated by an acoustic alert accompanied by a small indicator light.

A sensor, installed on the appliance, detects the activation of the indicator light and transmits the signal to a dedicated lamp, which lights up using integrated LEDs. In this way, even if located in a different room, the user is able to monitor the status of the appliance easily and effectively.

This project was created by Crotti Celeste, Ferravante Martina, Fiorani Maddalena, Mazzi Leonardo, and Miguel Katsamakis Alexandra for the Fab Lab exam.

_Materials needed:

Cut pieces

Bolts and nuts

Vinyl glue

Screwdriver

3D printed media

Grooved slots and guides

3D printed semi-transparent shell

Bolts and nuts

Arduino and its code

_Step by step procedure:

1. Arduino configuration:

Before assembling the two boxes, configure the Arduino by writing the necessary code.

Send the code to the Arduino using the appropriate software.

2. Components:

Cut and print all the pieces you need.

3. Sensor box:

3.1 Fixing the breadboard:

Place the 3D printed media on the base of the box.

Fix the breadboard on the holder, which also acts as a lock.

3.2 Assembly of parts:

Use bolts and nuts to join the pieces, helping you with the screwdriver.

For parts that require bonding, apply PVA glue, except the base which is fixed with 4 bolts.

4. Lamp:

4.1 Mounting of breadboard, relay and battery:

Place the 3D printed media on the base of the box.

Attach the breadboard, relay and battery to the holder which also acts as a lock.

4.2 Assembly of parts:

Use bolts and nuts to join the pieces, helping you with the screwdriver.

For parts that require bonding, apply PVA glue, except the base which will be fixed later

4.3 Passage of wire:

Run the wire through the semicircular slot on the top side of the box.

Roll the wire following the grooved guides of the piece.

4.4 Closing the box:

Insert the 3D printed semi-transparent shell, inserting it into the slots at the base.

Close the base with 6 bolts and nuts.
