Just released:
A beginner's guide (and review, for seasoned users) of a simple module with an easily driven LCD screen, and 5 input buttons. Costs $12 or £11, plus p&p, assembled and tested. You just plug it in. (US and UK sources listed)
For the five buttons: Uses one analog input
For the LCD: Uses 7 lines of digital IO.
Module can be used as a shield on an Uno, Diecimila, Duemilanove or Freeduino. For others, it is a simple matter of a few interconnect wires. All explained at page listed above.
The page IS new... feedback on anything that isn't clear would be welcome.
