Este teclado LCD Shield (pin conector macho) para Arduino se compone de un 6 pulsadores momentáneos 16x2 azul pantalla LCD y, de izquierda a derecha, SELECT, izquierda, arriba, abajo, derecha y RESET. El escudo puede ser conectado directamente a una placa Arduino Duemilanove, por lo que la soldadura o volar-cableado para la conexión innecesaria. Botones 5, 6, 7, 8 y 9 se utilizan como la interfaz para la pantalla LCD.

caracteristicas:
• Fácil de leer 16x2 pantalla de cristal líquido azul
• Contraste ajustable
• El diseño laminado y fácil de ampliar
• Uso de la interfaz LCD4Bit modificado

Interfaz LCD4Bit modificación:
Con el fin de preservar el puerto SPI para uso futuro, los pines IO Digital DB7-10 y pin11 y 12 pines usados ​​en la biblioteca LCD4Bit original se han trasladado a DB4-7 y el pin 8 y 9 pines respectivamente.

teclado:
El teclado consta de 5 pulsadores - SELECT, izquierda, arriba, abajo ya la derecha, más un botón RESET. Para guardar el recurso pin IO digital, la interfaz de teclado sólo utiliza un canal ADC. El valor de la clave se lee a través de un divisor de tensión de la resistencia de 5 etapas. Cuando se pulsa una tecla, el ADC lee el valor de la tensión a través del divisor de tensión; entonces el valor de la tensión se compara con el valor umbral de la tensión almacenada en una matriz para identificar qué tecla se ha pulsado.

Especificaciones:
Tensión de funcionamiento: 5 V CC
Dimensiones: 80 x 58 x 22 mm
Peso: 52g

* Nota: Este no es un producto original de marca Arduino.

The pin out for this dispay shield is as folows (display-arduino): D4-4, D5-5, D6-6, D7-7, RS-8, E-9.

Buttons have a nice click to them and are all (except reset) readable from pin A0 (schematic for how they are conected would be nice HK)

When pluged in to an arduino it interferes a bit with the power jack but not a whole lot, the board itself sticks about 1cm over the left edge of arduino.

I've tested this with arduino due which is 3,3V, the display works prfectly, the same cant be said for the buttons as they are powerd from 5V, some hardware hackong will be required.

Other than that it feels like a decent quality product, the soldering is ok, I'd like to see more solder in a couple of places, but over all good for the price.

The Arduino LCD screen is a backlit LCD screen with headers. You can draw text, images, and shapes to the screen with the LCD library. There is an onboard micro-SD card slot on the back of the screen that can, among other things, store bitmap images for the screen to display.

Works well, is very easy to use... just plug in shield, and you're good to go! Hobbykings documentation could have been a bit better though.

Use LiquidCrystal lcd(8, 9, 4,5, 6, 7); in order to control the LCD, IO pin 10 to control the backlight (recommend you use pinMode(10,INPUT) to turn on, and pinMode(10,OUTPUT) to turn it off).

Only uses one analog pin (A0) for the five control buttons - you just need to work out the different voltages that you'll read when you press each button - which will vary slightly depending if powering Arduino from external power or USB. 6th button is linked to reset line.

This is a cool little shield. Good price. I personally haven't found much use for it, but it was cool when I first got it up and running. I did a more in depth review at the address below.

For the money you can't buy this and make it yourself. I'd put this on your must have list.

Mine works as advertised. If you do a google search on 'LCD keypad shield', the top returns are the pages for this device from therobotshop_dot_com. There are schematics and excellent code examples.

I have a couple of possible uses for mine - hopefully I can port the code from the 3DRobotics ground station. I also tested it with a 4 x 20 display that I have and it works too.

Very nice device at an extremely good price.
