LCD Keypad Shield for Arduino Duemilanove & LCD 1602 (Works with Official Arduino Boards)

Pros: * Very bright. * Nice soldering (good quality imo). * CONFIRMED: Works with Arduino! * Also works using the standard LiquidCrystal library. Please note: The data-pins are -not- arranged as they are for the Hitachi-driver! Therefor, the Arduino Example-sketches will NOT work by default with this display! To make the display work, use the following sequence of pins when starting the library: LiquidCrystal lcd(8, 9, 4, 5, 6, 7); I LOVE this display! It's so easy + reading all the buttons only takes one analog in! (it adds up the analog value trough resistors)

Cons: It doesn't say anything about the pin-setup for the liquidcrystal-library, so I had to find that out myself, which took an hour or so. Other than that I really can't find any cons with this display!

Other: This is -totally- worth the price! It's a bright and solid display that is easy to read and very simple to use with the Arduino!

Pros: It has a very bright LCD screen and is totally compatible with the Arduino UNO. It is based in the HD44780 Nu electronics LCD shield. Easy connection shield and very robust construction. Paid half the cost of the same shield in a local shop. You can see the schematics here: http://www.nuelectronics.com/download/projects/LCDshield_v1_1.pdf (With actual pinout configuration)

Cons: Different pinout configuration than the one used for the examples. It's tricky to set up for first time. In order to make it work with the provided Arduino IDE examples you have to modify the LiquidCrystal lcd definition line to "LiquidCrystal lcd(8, 9, 4, 5, 6, 7);" Then everything works fine and smoth. There are no ICSP jumpers in this board, so, if you need them you'll have to solder them by yourself.

Other: A must buy if you do any project with Arduino

Pros: Very good contrast.
Clearly readable.
Compatible with the Arduino LiquidCrystal Library.
Provides a reset button to replace the one it hides.

Cons: Prevents easy access to the pins it does not use.
(The breakouts aren't solderless.)

Other: Great deal if you need to display anything in real time or away from a computer!

Pros: It Just Works! Had to turn the pot to the right, and change the pin numbers from the default Arduino sketch, but both have been described adequately by others in reviews/comments for this item. When I did this, I got it to work within 10 minutes. (I purchased this together with sku 118036, in combination with which it works flawlessly)

Cons: No documentation included, but if you read the other reviews/comments, that is not really a problem

Other: If you need a display for your arduino, this may very well fit you. Others may have had problems, for me it worked more or less from the start

Pros: This is a nice shield. I use it with the nano which with a few wires from the shield to the nano works fine (you only need 8 wires to make it work, 6 data + 5V & GND) Display is clear & it is working with the standard LiquidCrystal library as long as you start it with LiquidCrystal lcd(8, 9, 4, 5, 6, 7) instead of the default from the sketches (actually as I do my own wiring for the nano I could easily match it if I wanted to)

Cons: For me the potmeter was trimmed completely wrong. I thought the display was not working. (It lights up, buth nothing is seen) You need to spin the screw many times until something is visible. After I found that it worked like a charm. Too bad it took me lots of googling to find that simple resolution.

Other: Well worth the money, must have if you want to display data in a nice way in your project.

Pros: It is very cheap Easy to connect to arduino, you should just be sure that the pins are totally inserted. The keypad is very useful if you want to use this lcd to monitor the sensor outputs and control the inputs without any computer. It is very easy to program it.

Cons: I did not find anything problematic about it and I think there is nothing wrong.

Other: It is just good and cheap.

Pros: - Has a very clear LCD screen. - Has a very nice and bright blue backlight. - Its 2x16, so you'll have enough character headroom. - Has buttons that make a menu structure easily available, these are connected to Analog pin 0. - Has optional space to solder new headers on for connection on top of the LCD shield.

Cons: - It did not work at the start, because the contrast potmeter was turned the wrong way. - The setup pins are different from the original Arduino programs. Remember to change the LCD setup line to "LiquidCrystal lcd(8, 9, 4, 5, 6, 7);" Only then it will work properly. - The buttons work by adding an analog value to A0, but this does not detect multiple buttons. - Some of the extra soldering points to solder headers onto, do not line up with the original headers.

Other: Great product, If I needed more, I'd buy it again without hesitation.

Pros: Direct plug in and program makes it work Digital pin D10 is wired in for PWM control of LED backlight brightness Only uses the A0 input line to read the 5 buttons Other unused analog and digital lines are solder holes available to be wired in. Works fine with Arduino Uno, Arduino Duemilanove, and Nano (but you must wire that board separately instead of simply plugging it in). Best price found for this type of LCD built into the keypad PCB anywhere on the Internet and well below 1/2 price of some dealers. Free shipping is a big +++

Cons: Quality control is up to you. These have not been tested for functionality before shipment. Found solder bridge between 2 data lines making one module non-functional. Was easily detected with a magnifying glass and fixed with the touch of a soldering iron. Contrast adjustment is via a multi-turn pot and is tied to supply voltage rather than the regulated +5V. That means when powered by USB, the contrast will be way off from when it is powered by a 9V battery and you have to turn the pot a lot of times to be able to see the display. Out of the box, it took a lot of turns just to make it visible when plugged into the USB.

Other: Excellent module at the best price around. If it doesn't work out of the box, do some quality control inspection. The fix is probably a quick one.

Pros: Product well designed and ready for use. Just plug and play. Note that board has to verify the connection. In my case it worked without problems with an Arduino Mega. Verify that the keys are connected to analog inputs. With the examples in internet you can quickly develop a simple menu. Working with analog inputs for the buttons you may not learn well the concepts of rebounds that occur with digital inputs and buttons. Reading the examples for Arduino will learn quickly the operation of the module.

Cons: Not bad, but I do not like that the buttons are connected to the analog inputs.

Other: Good product that works right out of the box.

Pros: -works great when you have figured out how it works -cheap -great display

Cons: it took me some time to find a library for it in C when u need help just contact me (kevin__114@hotmail.com) as already noted in other reviews you have to turn the potentiometer but when you know that it is not a real con

Other: a great device for DIY projects when you need buttons and a display to show useful informations
