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.

Alliance of Droids - Companion Robot - Help needed!

Hello everyone. Just so everyone knows, I am an absolute beginner when it comes to electronics and that sort of stuff. I built my own R2-D2, but it wasn't motorized.

I want to build a companion robot for the Alliance of Droids - my charity. I was planning to use some Arduino's for the project, as well as a controller system.

I want to know the estimated cost, the parts I would need, and some more information.

If anyone would be interested in helping me, please visit my website @ www.allianceofdroids.com.

Thansk for your help.
