Arduino Handheld Prototyper
Last month, we started a three part series on an Arduino-based handheld prototyper shown in Figures 1 and 2 (with the base artificially tinted blue
so that it can be seen better). The Arduino handheld prototyper— as the name
implies — lets us develop prototypes that are portable (in our very own
hand), and provides a bonus that is lacking in the stand-alone Arduino: It can
accept user keypad input via pushbuttons, and provides the user with visual
output via an LCD. This device consists of three main parts: an Arduino proto
shield, an I2C mini terminal, and a base kit that holds them together. We
introduced the I2C mini terminal last month. Now, let's look in more detail at
the software for that device.

Using The I2C Mini Terminal Software
68 August 2013
The IMT (I2C mini terminal) software provides some
simple and easy to use Arduino library functions that we
saw last month in our mini_terminal_master demonstration
program. We learned that by simply putting the
Mini Terminal directory in the Arduino installation Libraries
directory, we could use the Arduino IDE menu item
