Descrizione

Questa tastiera LCD Shield (pin maschio) per Arduino è composto da un display LCD blu 16x2 e 6 pulsanti momentanei, da sinistra a destra, selezionare, sinistra, su, giù, destra e RESET. Lo scudo può essere collegato direttamente su una scheda Arduino Duemilanove, rendendo la saldatura o volare cablaggio per il collegamento inutili. Perni 5, 6, 7, 8 e 9 sono utilizzati come interfaccia per il display.

Caratteristiche:
• Facile da leggere 16x2 schermo LCD blu
• Contrasto regolabile
• Design laminato e facile da ampliare
• L'utilizzo dell'interfaccia LCD4Bit modificata

Interfaccia LCD4Bit modifica:
Al fine di preservare la porta SPI per uso futuro, i perni digitale IO DB7-10 e PIN11 & pin 12 usati nella biblioteca LCD4Bit originale sono stati spostati DB4-7 e, rispettivamente, il pin 8 e 9 pin.

tastiera:
La tastiera è costituita da 5 pulsanti - SELECT, Sinistra, Su, in basso ea destra, più un pulsante di reset. Per salvare la risorsa pin digitale IO, l'interfaccia della tastiera utilizza un solo canale ADC. Il valore della chiave viene letto attraverso un 5 fase di tensione divisore di resistenza. Quando si preme un tasto, l'ADC legge il valore di tensione attraverso il partitore di tensione; allora il valore di tensione viene confrontata con la soglia di valore di tensione memorizzato in un array per identificare quale tasto è stato premuto.

Specifiche:
Tensione di funzionamento: 5VDC
Dimensioni: 80 x 58 x 22 millimetri
Peso: 52g

* Nota: Questo non è un prodotto di marca originale 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.
