This unit works better than I thought it would. The select button on mine is a little bit flaky, but the resistor cascades on the buttons are more accurate than I expected. analogRead(A0) returns consistent values down to the 10th bit when a button is pressed. The D10 issue that had plagued some versions of the LCD displays has been addressed and fixed. The display is insanely simple to write to. The supporting links supply all the info necessary. It took all of 10 minutes to get it working.
