The FLORA main board is like a tiny computer (see Figure 3-1 ).
Its “brain” (a microcontroller) runs a small program, or set of
instructions looking for information from sensors and control-
ling devices connected to it based on the instructions in the pro-
gram. FLORA is Arduino-compatible and designed specifically
for wearable electronics projects. It's round, so it won't snag on
or poke through fabric; it's small, slim, and easy to sew because
of its large pads in a convenient arrangement. It's built around
the Atmega32u4 chip, located at the very center of the board.
FLORA can communicate with your computer over a USB cable,
which also supplies electricity to the board when its connected.
You can put new programs on it with the Adafruit Arduino IDE,
discussed in Chapter 2 .

FLORA's processor, the Atmega32u4, is the same chip inside the
Arduino Micro, Arduino Leonardo, and Teensy platforms, but it
