Shirt Pac-Man

This is an old revision of the document!

This shirt carries 14 LEDs sewn into Charlieplexing to occupy less outputs and thus improve the project in the future.

How create the circuit:

As seen in the diagram, pin Nº2 (Blue) connects with the positive of led 1 (green) and pin Nº3 with the negative of led 1. So, LED 1 will turn on. Since the current cannot flow through LEDs in reverse bias, the LED2 will stay off. If charges at the poles 2 and 3 are reversed, the LED 2 lights and LED 1 will turn off.

For 6 leds, it would be like that:

For this circuit to work as the previous one, we must disconnect one of the pins before applying the load to the remaining two. This can be solved by using the logical properties, the three states of pins. The pins usually have three states, HIGH, LOW and INPUT.

The input mode puts the pin into a high impedance state, electrically speaking, “off”, i.e., little or no current will flow through it. This allows the circuit select any number of pins connected at any time, simply changing the state of the pin.

In order to control the matrix of 6 LEDs shown, the two pins for the LED that we want activate must be connected to HIGH and LOW respectively, while the third pin is in its INPUT state. Doing it like that, prevents leakage of current off the third pin, ensuring that the LED you want to light is the only illuminated.

Circuit:

I used tape to prevent some wires touch.

Code:

const int LED_1 = 2;     //LED row 1   Definimos donde esta pinchado la primera linea de charlieplexing
const int LED_2 =3;     //LED row 2    Definimos donde esta pinchado la segunda linea de charlieplexing
const int LED_3 =4;     //LED row 3    Definimos donde esta pinchado la tercera linea de charlieplexing
const int LED_4 = 5;     //LED row 1   Definimos donde esta pinchado la primera linea de charlieplexing
const int LED_7 = 6;

To hide the battery I have cut a square of 6×6 cm and I made a pocket folding inward 1cm and sewing machine.

Connect the battery to some jumpers and bend the extremes with help of pliers until have a properly shape to sew them. Continue sewing to create two connections with some snap fasteners.

In another shirt sew at the same height the corresponding snap buttons (on the reverse side).

Iron the vinyl figures with Pacman shape matching with the path of the leds of the other shirt.leds of the other shirt.leds of the other shirt.leds of the other shirt.

Vinil: https://drive.google.com/file/d/0B6qTJd3wtrO5b2NYTXdMQVQtckk/view?usp=sharing

We already have the shirts connected, we must now create a slider.

Cut 2 10×4 cm strips, sewing them together with conductive thread to be placed on the bobbin of the machine. I used textile vinyl to isolate. Sew the extreme with conductive thread making it match with the snap fasteners on the shirt without the circuit.

To create the button you must cut 3 squares of 4x4cm, iron a circle of textile vinyl in one of them to decorate, sew them and fill them with sponge cut to the same size.

In one of them, we will sew on one side a piece of conductive fabric of the same size and join it to the button, creating a sliding button that rides on the previous piece ensuring that the part with conductive fabric touches the stitching conductive thread thus the circuit is closed and the lights turn on.ensuring that the part with conductive fabric touches the stitching conductive thread thus the circuit is closed and the lights turn on.

I would like to share with you my last personal work, I was inspired by Jie Qi, I have been following her for a long time and admire her talent. I hope you like it and especially thanks to Jie.

We started with the pattern, this time I cut it in the traditional way because the fablab laser is (60X30cm).

The fabric used is:

Chiffon 3m

Muslin 2m

https://drive.google.com/file/d/1A0JBQL_fc1HcGbTfx1Hm1R5tvc47unro/view?usp=sharing

Before sewing the dress is decorated with textile vinyl, in my case it is ironed at 167 degrees but look at your vinyl before ironing because not all are ironed at the same temperature.

I cut the vinyl with a 45ºC blade that is usually the basic one with these parameters:

Speed: 24

Power: 130

Iron at 167º (ask the seller, not all vinyls are ironed at the same temperature).

We sew all the pieces by machine, the circuit is sewn in the muslin to hide the components.

First I did tests with 3 leds.leds.

En caso de que sea positivo, va encendiendo cada uno de los leds por orden. Esto se puede convertir en funcion
/* Como establecer los cables en cada uno de los leds?
1) Ver el esquema del charliplexing
2) Establecer el pinmode de los cables donde esta conectado el led como OUTPUT. El resto de cables como INPUT
3) Los cables que usemos, pondremos el que corresponda a HIGH y el contrario a LOW
