    Gewoon een fantastisch product voor hele lage prijs! Je moet wel enkele weken geduld hebben .

    Works perfect with an Arduino Uno. Easy way to make a MMI for small projects.

    O brilho do potenciómetro azul deve ser ajustado com cada escudo. Gire o parafuso de controle aprox. 10 vezes no sentido dos ponteiros do relógio. Dos 3 escudos do teclado fornecidos, o display foi danificado durante o transporte com uma blindagem. Assim, 3 dígitos na linha superior não podem mais ser exibidos. Caso contrário, está bem. Portanto, apenas uma embalagem ruim ou um transporte ruim. Por essa razão, apenas 4 estrelas.

    Juste un petit souci de broches un peu tordues mais vite remisent en place. Attention, j'avais un écran LCD 16x2 "simple" et pour les croquis ce n'est pas pareil : Pour utiliser l'écran simple : LiquidCrystal lcd(12, 11, 5, 4, 3, 2); Pour l'écran avec boutons : LiquidCrystal lcd(8, 9, 4, 5, 6, 7); Une fois les bonnes valeurs misent, ils fonctionnent très bien.

    I'm in a robotics class in my High School where we all use Arduino Uno's and create programs. We had to order a part for the class so that we could improve our ability to do different things. I chose the 16x2 LCD display because I was already working on a "Drag Strip Light"-esque project and I could use the 16x2 display to display the timers when the objects crossed the finish line. My only problem was when I went to test it out with one of Arduino's "LiquidCrystal" examples only to find out they don't display on this shield because it has a different hardware setup than Arduino's variant. You have to go to SainSmart's website and download their Library and Sample Codes to be able to test this. If you're versed in C script you can figure out how to operate it.

    This model seems to have a hardware problem that may fry something: "In those backlight circuit designs, the problem is that the Arduino pin is shorting to ground through the transistor when the pin is high. Yes the backlight is on and it appears to be working but it is massively overloading the Arduino pin which may eventually cause problems and perhaps even burn out the pin." There is a discussion about it here http://tinyurl.com/p4l26y3 or you can google "Warning to users of some vendors LCD keypad shields." I just tested my keypad shield using a test sketch provided by user bperrybap and it reported "Bad Hardware". Seeing a potential problem I simply cannot give this product too many stars. Please correct my warnings in case they are wrong!!

    Good build quality but i have some trouble find the pin. Anyone have the datashit or pin scheme for the declaration of LCD? LiquidCrystal lcd(?, ?, ?, ?, ?, ?); Keypad work good with Arduino UNO and NANO Well delivery and packed good
