LCD Keypad Shield with black text and green-yellow backlight

An LCD display shield with built in reset button and 5 programmable buttons for Arduino UNO.

Note: Possibly the contrast of the display has to be calibrated with the blue potentiometer. This precise potentiometer can make 25 full turns!
When no text is visible, turn clockwise. When only blocks are visible, turn counter-clockwise.

Note: This product contains a design flaw that could cause pin D10 on your Arduino to be overloaded if it sends a high signal. Make sure you use software that does not control pin D10 or only controls via a low signal! See this page for more information about this problem: Arduino LCD Backlight Fix.
