Makes it really easy to add a LCD to your Arduino projects. The only con is that it doesn't have headers to add wires. It just have holes for you to solder your own headers. The LCD uses 6 ports and the keypad uses only one. Works fine with Arduino Leonardo and UNO.
Test avec une carte MEGA2560. Prendre le lien suivant : http://www.dfrobot.com/wiki/index.php?title=Arduino_LCD_KeyPad_Shield_(SKU:_DFR0009) Fonctionne super bien. Le réglage de l'écriture en blanc sur bleu par le potentiomètre a une forte amplitude, on arrive même a écrire bleu foncé sur fond bleu clair. Une étoile en moins car l'écran comporte un défaut mais en dehors de la zone d'affichage.
The one I received is the 1.0 version of the shield. The only difference are the resistor divider values for the button network. I soldered on some female headers to further connect some breadboard wires on top of this thing. Works great and best price I could find on the internets. The manual and example code for this device is located here: http://www.dfrobot.com/wiki/index.php?title=Arduino_LCD_KeyPad_Shield_(SKU:_DFR0009)
Cegou tudo ok, bom aspecto e qualidade. Arrived everything ok, good looking and quality.
Great value and no real issues. Like other people have mentioned a lot of the pins arrived bent and needed straightening. Its annoying but not a deal breaker. if you search the interwebs for "keypad shield test sketch" you will find a sketch to get you up and running. If your wondering how to line up the pins, just make sure the A0-A5 pins on the shield match with the A0-A5 on the board. One thing to note you may find there is no text on the screen in which case you will have to turn the potentiometer screw (the brass screw on the blue box in the top right) clockwise many many times before you begin to see the text.
As per http://forum.arduino.cc/index.php?topic=96747.0 there is a problem with the backlight control pin. With the board that I received if you attempt to use the backlight control you can potentially break the AVR in your arduino board. Otherwise the board works perfectly including the backlight, just don't try and switch the backlight off with pin 10.
Works very good. Tested with this code : http://www.dfrobot.com/wiki/index.php?title=Arduino_LCD_KeyPad_Shield_(SKU:_DFR0009). Just take the v1.0 values. The markings are not very well made, but all the electronics works great! I will buy more
توصيل سريع. التعبئة الجميلة. اختبار وظيفي يظهر أن كل شيء وفقا لوصف البند. تم تعيين مقياس الجهد عالية جدا، لذلك فمن الضروري ضبطه. استخدام مكتبة الكريستال السائل القياسية.
معبأة بشكل جيد، وتسلم في حالة جيدة ووقت تسليم ممتاز (9 أيام تقويمية من الطلب). اشتريت هذا فقط من أجل التجريب.
Works perfect
