Introducci\u00f3n del proyecto<\/strong><\/h2>\n<\/div><\/div>\n\n\n\n

Nuestro proyecto se basa en un esc\u00e1ner 3d con varias funcionalidades las cuales son: esc\u00e1ner, cinem\u00e1tica y control manual.<\/p>\n\n\n\n

La implementaci\u00f3n se ha llevado acabo con: varias piezas impresas en 3d como estructura del proyecto, una placa Arduino uno R3, regulador de voltaje DC-DC, bluetooth hc-06, motor paso a paso, driver controlador motor paso a paso, lcd 16×2, modulo I2C y m\u00f3dulo joystick.<\/p>\n\n\n\n

Implementaci\u00f3n<\/strong><\/h2>\n\n\n\n

LCD y Joystick<\/h4>\n\n\n\n

Primero empezamos viendo como presentar la interfaz a trav\u00e9s del m\u00f3dulo lcd, una vez que lo tuvimos claro, la implementaci\u00f3n se llev\u00f3 a cabo de la siguiente manera: Al tener el modulo I2C se utilizaron los pines A4 y A5, se utilizaron estos pines porque son los que viene por defecto en Arduino uno R3 para SCL y SDA que son las conexiones de comunicaci\u00f3n que sal\u00edan del m\u00f3dulo I2C. La librer\u00eda que se utiliz\u00f3 fue LiquidCrystal_I2C.<\/p>\n\n\n\n

Seguimos por c\u00f3mo implementar la navegaci\u00f3n del men\u00fa con el m\u00f3dulo joystick en funci\u00f3n de los valores que se obten\u00edan.  En este caso la conexi\u00f3n del switch que ten\u00eda el m\u00f3dulo joystick se conect\u00f3 al pin 8 digital y se configur\u00f3 como pin de entrada y a un valor alto, los pines de los ejes X e Y se conectaron a los pines A0 y A1 porque los valores que podr\u00edan tomar no son 0 \u00f3 1 sino que est\u00e1n entre varios rangos y para poder controlarlos se necesitaba una se\u00f1al anal\u00f3gica.<\/p>\n\n\n\n

Problemas encontrados<\/h5>\n\n\n\n

El n\u00famero de conexiones hac\u00eda la placa era muy elevado, esto, se subsano instalando un m\u00f3dulo i2c para el lcd y as\u00ed minimizar el n\u00famero de conexiones.<\/p>\n\n\n\n

Motor Paso a Paso y Driver<\/h4>\n\n\n\n

De esta parte se encarg\u00f3 Adri\u00e1n Leonis Garc\u00eda<\/strong>, pero cuando surgieron los problemas a la hora de combinar el m\u00f3dulo lcd y el motor paso a paso con el driver, buscamos una soluci\u00f3n entre los tres integrantes del grupo ya que nos cost\u00f3 bastante poder encontrar el camino a la soluci\u00f3n. <\/p>\n\n\n\n

Una vez realizado estos dos pasos nos pusimos en marcha con el motor paso a paso y el driver controlador del mismo. Primero hicimos una demo para ver como funcionaba, una vez que entendimos como funcionaba hicimos la relaci\u00f3n de pasos con los engranajes que ten\u00edamos, en este caso fue con prueba error hasta que se consigui\u00f3. Cuando quisimos juntos lo que ten\u00edamos realizado del lcd y el motor nos dimos cuenta que el m\u00f3dulo lcd empezaba a parpadear cuando giraba el motor. Esto nos llev\u00f3 un tiempo darnos cuenta c\u00f3mo solucionarlo y mucha b\u00fasqueda en internet. La soluci\u00f3n que implementamos fue sacar el voltaje de la energ\u00eda suministrada por el Arduino en este caso 9v y pasarlo por un regulador de voltaje que convirtiera de 9v a 5v necesarios para el driver del motor paso a paso.<\/p>\n\n\n\n

Problemas encontrados<\/h5>\n\n\n\n

La tensi\u00f3n demandada era muy elevada para poder combinarlo con el lcd se solucion\u00f3 este problema implementando un regulador de voltaje DC-DC el cual suministra la tensi\u00f3n al driver.<\/p>\n\n\n\n

M\u00f3dulo Bluetooth<\/h4>\n\n\n\n

Parte realizada por:  Erik Fern\u00e1ndez Orgaz.<\/strong><\/p>\n\n\n\n

Ahora ya solo nos quedaba el m\u00f3dulo bluetooth que tras una b\u00fasqueda exhaustiva por internet nos dimos cuenta que los comandos AT por los que se reg\u00eda el m\u00f3dulo bluetooth no nos val\u00eda para la implementaci\u00f3n que quer\u00edamos realizar. Encontramos un GitHub que pod\u00eda flashear el m\u00f3dulo haci\u00e9ndolo pasar de un hc-06 a m\u00f3dulo rn-42 de mejores prestaciones y con las funcionalidades que necesit\u00e1bamos. Una vez llevado a cabo esta operaci\u00f3n tuvimos el problema de c\u00f3mo comunicarnos con el m\u00f3dulo, nos dimos cuenta que el m\u00f3dulo trabaja con 3.3 voltios el pin de recepci\u00f3n, esto se resolvi\u00f3 con un divisor de tensi\u00f3n con resistencias de 1k ohm y 2k ohm.<\/p>\n\n\n\n

Problemas encontrados<\/h5>\n\n\n\n

Los comandos reconocidos por el m\u00f3dulo no eran suficiente para lo que necesit\u00e1bamos, la soluci\u00f3n fue flashear el m\u00f3dulo para que por firmware fuera un dispositivo rn-42 esto se llev\u00f3 a cabo con la ayuda de un m\u00f3dulo ftdi-usb en el cual se soldaron los pines del m\u00f3dulo ftdi-usb RTS,RSD,RI y DTR a los pines CLK, MISO, MOSI y CSB del m\u00f3dulo bluetooth respectivamente de la siguiente forma:<\/p>\n\n\n\n

\n\"ComunicacionBluetooth\"<\/a>\n<\/div><\/figure>\n\n\n\n

Esto nos permiti\u00f3 poder iniciar una comunicaci\u00f3n del dispositivo hc-06 al ordenador y con la utilizaci\u00f3n de las aplicaciones Bluesuite y Pstool se pudo llevar acabo el flasheo del dispositivo.<\/p>\n\n\n\n

Una vez realizado este paso faltaba configurar el dispositivo para que simulara un teclado y poder utilizar la tecla \u00abenter\u00bb para que hiciera una foto desde la aplicaci\u00f3n nativa de la c\u00e1mara del tel\u00e9fono, esto se llev\u00f3 a cabo con ayuda de la librer\u00eda BPLib referenciada en la bibliograf\u00eda de la presentaci\u00f3n hecha.<\/p>\n\n\n\n
