Forget the soldering iron, there’s no time for that! Instead, grab your box of littleBits™(see littlebits.cc) and you’re just about good to go. In order to
refresh your memory, littleBits is the incredible ecosystem
of building components that snap together with magnets
and enable you to go from wish list to completed project
is just a matter of minutes. In order to prove the power of
littleBits, here are five incredibly fun projects that can be
built in one evening — that’s all five projects in one sitting,
mind you! Let’s get going.
Bits in Toyland
Add a glowing wreath to your front door that only
lights up when the temperature drops to the overnight
lows that are common in your area. This project requires
the following Bits:
• Power p1
• Temperature sensor i12
• Threshold i23
• Light wire o16
Hey look at that, no other tools are required!
Figure 1 shows the four littleBits’ modules used in this
project connected together. The four foot long
electroluminescent wire that is connected to the o16
module generates the soft blue glow for the wreath. This
wire is very flexible and can be wound or braided into any
diameter wreath that is selected. Use some zip ties for
holding the light wire wreath in place.
After you’ve prepared your wreath, it’s time to plug all
of the modules together. In order to get the project to
properly turn on at the required temperature, you will
need to adjust both the temperature sensor (i12) and the
threshold (i23) modules.
Begin by setting the temperature sensor for measuring
the Centigrade scale. Next, install the entire glowing
wreath assembly in its planned location. Now, monitor the
temperature outdoors and when you’re satisfied with the
chill in the air, turn the threshold knob until the light wire
just illuminates. That’s it! Now, every night when the air
temps drop to the programmed threshold level, the wreath
TIP: If you have a littleBits number module (o21)
handy, you can temporarily remove the threshold and light
wire modules and add the number module to the
temperature sensor. Now as the air temps change, you
can actually read the temperature on the number module.
Then, you’ll know exactly what temperature the wreath
will glow at. Pretty nifty, eh?
On an Open Fire
Do you have a problem with late night “guests”
making trips to the Christmas tree and, shall we say,
“studying” the presents? Okay, let’s put it this way: Do you
have kids who sneak around at night peeking at the
presents? If so, then this monitor project is just for you.
Here’s what you’ll need:
• Power p1
• Sound trigger i20
• Wire w1 (might need several of these)
• Bargraph o9 or Cloud w20
