JUEGO DE LEDS CON ARDUINO

Los leds van formando un patrón y tenés que repetir la secuencia de luces formada al presionar un botón, cada sonido proviene de un piezo con su respectivo led.

Inicie el juego presionando uno de los cuatro botones. Cuando se enciende un led, presione el botón, repitiendo la secuencia. La secuencia se hará cada vez más larga.

El juego se gana después de 13 rondas.

Arduino:

Arduino es una plataforma de creación de electrónica de código abierto, la cual está basada en hardware y software libre, flexible y fácil de utilizar para los creadores y desarrolladores.

Placa de prueba:

En ella se pueden insertar elementos electrónicos y cables para el armado y prototipado de circuitos electrónicos.

Resistencias:

Los componentes electrónicos llamados resistencias se utilizan en los circuitos para variar los valores de intensidad y voltaje.

Pulsador:

Es un interruptor o switch cuya funcion es permitir o interrumpir el paso de la corriente electrica de manera momentánea, a diferencia de un switch comun.

Piezo:

Es un dispositivo que permite convertir una señal eléctrica en una onda de sonido. Estos dispositivos no disponen de electrónica interna, por lo que tenemos que proporcionar una señal eléctrica para conseguir el sonido deseado.

Leds:

Un diodo emisor de luz o led es una fuente de luz constituida por un material semiconductor dotado de dos terminales.

Jumpers:

Es un elemento que permite cerrar el circuito eléctrico del que forma parte dos conexiones.

1. Colocamos 4 leds en nuestra placa de pruebas.
2. Colocamos los resistores en la pata positiva del led (ánado).
3. Hacemos las conexiones con sus respectivos pines.
4. Colocamos 4 pulsadores en nuestra placa de pruebas, cada uno pertenece a un led.
5. Colocamos un piezo conectando ambas patas a los pines del arduino
6. .Conectamos nuestro arduino a la PC y cargamos el código.
7. Ejecutamos el código y compramos el funcionamiento del proyecto.

Video de Ensamblado de los Componentes

Utilizamos la plataforma Tinkercad para realizar una maqueta del proyecto, para tener una idea de cómo queremos que se vea el proyecto visualmente.

SparkFun Inventor's Kit Example sketch 16 Spark Fun Electronics Oct. 7, 2014 Simon Says is a memory game. Start the game by pressing one of the four buttons. When a button lights up,  press the button, repeating the sequence. The sequence will get longer and longer. The game is won after  13 rounds. Generates random sequence, plays music, and displays button lights. Simon tones from Wikipedia - A (red, upper left) - 440Hz - 2.272ms - 1.136ms pulse - a (green, upper right, an octave higher than A) - 880Hz - 1.136ms, 0.568ms pulse - D (blue, lower left, a perfect fourth higher than the upper left)  587.33Hz - 1.702ms - 0.851ms pulse - G (yellow, lower right, a perfect fourth higher than the lower left) -  784Hz - 1.276ms - 0.638ms pulse Simon Says game originally written in C for the PIC16F88. Ported for the ATmega168, then ATmega328, then Arduino 1.0. Fixes and cleanup by Joshua Neal <joshua[at]trochotron.com> This sketch was written by SparkFun Electronics, with lots of help from the Arduino community. This code is completely free for any use.

Para cerrar, primeramente, queremos agradecer a Samsung Innovation Campus por la disposición que tuvieron para enseñarnos, gracias a SIC, aprendimos una variedad de temas, compartimos experiencias.

La finalidad que encontramos en este curso, es el de poder compartir conocimientos entre todo para buscar soluciones innovadoras a problemas que nos encontramos en nuestros alrededores.

El Arduino puede ser un gran pasatiempo en el que no gastarás mucho dinero y que podrás compartir con otros amigos que también amen la tecnología.
