COLOR-CODED BY FUNCTION
BitsTM are grouped into four dierent
categories, which are color-coded.

(“X” ICONS)
POWER (BLUE): Power Bits, plus a power
supply, run power through your circuit.
INPUT (PINK): Input Bits accept input
from you or the environment and send
signals that aect the Bits that follow.
OUTPUT (GREEN): Output Bits do some-
thing – light up, buzz, move…
WIRE (ORANGE): Wire Bits connect to
other systems and let you build circuits in
new directions.

MAGNET MAGIC!
Bits snap together with magnets. The
magnets are always right – you can’t
snap them together the wrong way.
C
ARROWS SHOULD POINT IN THE SAME DIRECTION
IF THE BITS WON’T SNAP TOGETHER, TRY SPINNING
ONE AROUND AND MAKE SURE THE ARROWS POINT
IN THE SAME DIRECTION
ORDER IS IMPORTANT
POWER BITS always come rst and
INPUT BITS only aect the OUTPUT
BITS that come after them.
D
WITH NO OUTPUT BIT AFTER IT, THE INPUT BIT HAS
NOWHERE TO SEND ITS SIGNAL
THE INPUT BIT AFFECTS THE OUTPUT BITS THAT FOLLOW

2ADD THE ARDUINO®BIT TO YOUR CIRCUIT AND PLAY WITH IT. The Arduino
Bit changes how your circuit works because of the code loaded on it. You can
change what the Arduino Bit does by changing that code.

p1 POWER MEET THE BIT
Every circuit starts with
power. It provides the juice
that makes your Bits™spin,
buzz, blink, and shine.
The power Bit converts the
9 volts of electricity in the
battery to the 5 volts that
littleBits™circuits run on.
The power Bit also sends a
signal through your circuit.
Manipulating this signal
with inputs is how you
control your circuit.
The p1 power is for use
only with a 9 volt battery.
