Checking operations before assembly
Operating the Japanino and LED unit with batteries
How to assemble the supplement
2
Insert the connectors from the battery box, the LED unit, and the
speaker in the main unit casing into the relevant connector plugs on the
Japanino as shown in the diagram, and then turn the switch for the battery
box on. If the LEDs are flashing, then everything should be working.
3
Touch the lead switch. If a beep sound is emitted, everything should
be working.
* Be sure to check
the orientation of
the batteries.
If something isn't working properly…Check the following!
●
Are the batteries new, and have they been inserted in the right direction?
●Did you plug in each connector in the right place and push each all the way in?
●Is the switch for the battery box turned to ON?
●Is the power supply LED on the Japanino main unit (see page 6) lit up?
Note: If you are unable to check that these operations are working
correctly, you will not be able to check the operations on page 6.
Please make sure to check.
How to hold the connector.
Insert the connector into pins D6 to GND.
Insert the connector into
pins A0 and GND.
* If the beep sound continues even after you've
taken your hand away, adjust the amount of space
between the terminals on the lead switch so that
there is about 0.5 mm of space between them.

Assembling the P.O.V.
1
Affix the speed-increasing gear to the main unit casing with a washer
head screw (being careful not to tighten them too tightly).
2
After passing the tip of the LED unit through the top of the main unit casing, affix
the LED unit to the main unit casing with a washer head screw (being careful not to
tighten them too tightly).
3
Screw the lead switch down with the screw (small). Next, screw in the
connecting rod with washer head screws.
4
Pull the cable up as shown in the diagram, and then screw in the back
cover using washer head screws.
* Pull the cable up toward the top
to screw in the screw.
* The back cover is attached to protect
the main unit. You do not need to
attach the back cover if you wish to see
the mechanisms inside the main unit. It
will still operate without the back cover
attached.

When Attaching Stands to the
Japanino…
5
Loosen the cable holder that is wrapped around the speaker cable. After
passing the LED unit and speaker cables through as shown in the diagram,
affix the cable holder using a washer head screw. Tighten down the loosened
cable holder once again.
6
Attach the handle gear and handle knob from the front side with washer
head screws to complete.
One cable holder comes already
attached to the main unit casing as
shown in the picture below. This
cable holder is to be loosened.
Attach stand A and stand B by screwing in screws in four places as shown in
the diagram.
* Turn the handle clockwise
to lightly check if the LED unit
swings left and right.
Note: You need not attach the stands if doing so prevents you from being able to insert the Japanino
into the USB slot on your computer. However, in such cases, please take extra precautions to ensure
that the back side of the Japanino does not come into contact with metal during use (if that should
occur, electricity may flow unexpectedly, causing the board to break). Leftover screws can be used
for other DIYs.

1
Insert the connectors for the
completed P.O.V. and the battery
box into the connector plugs on
the Japanino (see page 3 for where
to insert). Turn ON the switch on
the battery box. If the LEDs are
flashing, then everything should
be working.
2
Turn the handle on the P.O.V. to
make the LED unit swing slowly
left and right. If a beep, beep, beep
sound is emitted on the left side,
then everything should be
working.
Connecting the Completed P.O.V.
to the Japanino to Check
Operations
How the P.O.V. works
If something isn't working properly…Check the following!
●
Did you plug in each of the pins on the connector firmly into the right place?
●
The speaker will emit sound if the lead switch makes contact with the speed-
increasing gear when the projection on the gear is on the left side. Slowly turn
the gear to check it.
Note: If you are unable to check that these operations are working
correctly, you will not be able to try out the experiments on page 9.
Please make sure to confirm that these operations are working.

Insert three new AAA batteries
into the battery box.
Turn it
ON.
Pass the tip
of the LED unit all
the way through.
* Either of the wires, grey or black, can
be inserted into the GND pin.
* If the LED unit is left on the left side,
the speaker continues to emit the beep
sound.
Once you've checked everything, turn the
battery box OFF, and unplug the connectors
from the Japanino.
