产品介绍

该LCD键盘盾(男针连接器)用于Arduino的包括16×蓝色液晶显示屏和6瞬间按钮,从左至右,SELECT,左,上,下,右和RESET。屏蔽可以直接插在一个Arduino Duemilanove板,使得焊接或飞线连接不必要的。销5,6,7,8和9被用作接口到LCD。

特征:
•易于读取的16×蓝色液晶屏
•对比度可调
•夹层设计,易于扩展
•使用修改LCD4Bit界面

修改LCD4Bit接口:
为了保存SPI端口以备将来使用,在原LCD4Bit库使用的数字IO引脚DB7-10和PIN11和12脚已经被转移到DB4-7分别销8引脚9。

键盘:
键盘由5个按钮 - 选择,向左,向上,向下和向右加一个RESET键。要保存数字IO引脚资源,键盘接口只使用一个ADC通道。密钥值是通过一个5级的电阻分压器读取。当按下一个键时,ADC通过读取分压器的电压值;然后将电压值与存储在数组中,以确定被按下的键的电压值的阈值。

眼镜:
工作电压:5VDC
外形尺寸:80×58×22毫米
重量:52克

*注:这是不是一个原始的Arduino品牌的产品。

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.
