Quiet, but not dormant

Haven't posted for a while on LMR, but that doesn't mean I'm not working on a robot! I've researching the heck out of circuitry and components that I need for my latest project. The chassis is built and the insides are coming together.  I don't want to post it just yet, but it's name is I-CORA.  Since my background isn't in electronics, I've been reading books and teaching myself logic circuits and PICAXE. With three kids and a busy job it takes a few weeks to get thru a book. I have several I"m reading now to try to get smart enough to get design the circuitry I need.

Basic I2C HD44780 LCD/Keypad Backpack

 

Practical Maker's I2C HD44780 LCD/Keypad Backpack is a basic, inexpensive little LCD backpack that is unique in that it combines a standard 4x3 keypad input with a standard  HD44780 LCD.  It has all of the necessary housekeeping functions like set cursor, cursor left, cursor right and backspace as well as basic single digit key press input /recognition.  All on a single I2C address using the normal Arduino Wire library.
