Advanced Note:
Ensure Both Motor board and Sensor
Shield have the indicated jumper
displayed with a yellow circle. If the
pins are missing the jumper, feel free to
short the pins by bending them to touch
each other or use a breadboard wire.

Heat Shrink (Optional) Soldering Iron Brass Sponge (Optional)
Screwdriver (+)
Frame Assembly:
Unwrap the paper that has the frame,
motor, battery holder and various
components secured together.
Peel both sides the acrylic paper.
You can start from either side top corner
and work your way down.
For this manual I will only remove one
side for ease in visual demonstration.

Motor Mounting Brackets are used to fixed
the DC motors to the frame.
Slide the bracket into the slot indicated in
the red circle and flip the unit to start
mounting the motors!
Ensure the dot is facing inwards when
assembling the frame to the chassis.
Shown with a green circle.
The wire leads will be facing outwards.
The motors will be facing the bottom.
Shown with the red arrow.
Using a soldering iron, solder the red wire to
the pin that is the farthest from the frame
and the black cable to the pin that is the
closest to the frame.
(You can also wire twist the cable onto the
motor)
Place another Motor Bracket on the
outside, the grove will allow for the
bracket to slide in.
Using the long screw provided, slide it
into the two brackets and motor.
To fasten the nut, gently squeeze the
motor and bracket and push the unit
outwards. You may also use a needle
nose to fasten the nut.
Use the brass spacers and Philips screws and
mount the nylon wheel on the same side as
the motors.
The wheel will align over the circled holes.
Must insert two
long screws.
Repeat for the
other side.
Flip over and secure
with screws.

Pinch horizontally indicated with red
arrows.
The switch should slide in smoothly
without braking the frame.
On the same side where you can see the
switch markings I and O, Install two nylon
M3 standoffs indicated with red arrows.
Use hex nuts provided with the standoffs on
the other side.
The area with the green circle, place a
standoff and secure on the other side using
another standoff. (Do not use a hex nut)
This will act as a stress relief for the arduino
and a mount on the other side for the H-
bridge.
Use two philips screw to fasten the
arduino to the frame.
This is the same side with the switch
marking.
ENSURE THIS BOARD HAS THE JUMPER IN
YELLOW IN IT.
Should you find that the jumper is missing,
use one strand from the rainbow jumper
wire set to make a short circuit or bend the
pins to the point where they are touching
each other.
Switch button is facing the
opposite side of the motors.

Verify the jumpers located with the
yellow circle are also attached.
Place the Shield over the arduino
microcontroller as shown.
A section below will explain how this shield
works.
Flip the car over where the motor and
nylon wheels are located. You can see
the nylon spacer for the h-bridge.
Place another nylon spacer in the red
circle and secure it on the other side
with a phlips screw.
It should look something like this when you
place the h-bridge.
Use only one hex screw to fasten the h-
bridge to the chassis.

Flip the car over to the side with the
arduino.
From the servo pack install the servo
plastic frame by sliding the motor into
the bracket on one side and repeating
for the other.
Secure it using a sharp screw bit found in
the servo pack.
Using a screwdriver or drill bit, enlarge the
hole to hold three m3 screws.
Slide the top servo bracket into the
bottom frame. The gears should align
and fit.
Ensure by hand that the motor can turn
left and right 90° or more, if this is not
possible remove and readjust before
proceeding!
Take a small sharp screw and insert into
the location of the red circle.
Place the few remain spacers and shown in
the image.
Fasten on the other side where the motors
are located with some hex nuts.
Flip the unit and insert another nylon
spacer for the battery holder. Fasten on
the other side with a hex nut.
Note: Insert the nylon spacer where the
red circle is, ignore where the nylon
spacer is currently in the photo.

Insert the servo bracket and mount over the
three nylon spacers and fasten the screws
into the female thread of the spacers.
Note: you can turn the bracket at an angle to
access the screws.
Flip the unit and fasten the battery
holder on the single standoff.
You can also insert the wheels now or
later after completing the wiring.
Wiring Guide:
You can use a jumper
wire and strip the ends
for the cable to supply
power to the Arduino
terminal block from the
motor shield terminal
block.

How the Sensor Shield Works:
The select jumper allows the voltage from the
terminal block to enter and become regulated to
5VDC for the Arduino microcontroller.
If the jumper is not present, you must connect a dc
connector into the Arduino dc port.

The highlighted column is referred to as the 5v bus.
Instead of having multiple servos or sensors
connecting into a single 5VDC port this bus reduces
crowding and makes connections convenient.
Same principal as the 5V bus, this is called the
ground bus.
Pinout on the left image highlighted are equivalent
to the image on the right with the red box.
This is used for digital sensors.
The highlighted section is for analog signals and is
equivalent to the image on the right with the red
box.
Programming Arduino with the Code
1) Plug Arduino Microcontroller into computer using the blue USB cable provided
2) Install the Software to read and write program to the chip from ARDUINO.CC, the program is
free! << https://www.arduino.cc/download_handler.php >>
3) Download the driver from this link: << http://sparks.gogo.co.nz/ch340.html >>
For windows please download from here: <<
http://sparks.gogo.co.nz/assets/_site_/downloads/CH34x_Install_Windows_v3_4.
zip >>
4) Open the Arduino software and select the com port to program the microcontroller.
5) Download our premade software from our website or following this link
<< https://abra-
electronics.com/index.php?dispatch=attachments.getfile&attachment_id=134 >>
6) Extract the file and open one of the example codes, it will open in the arduino software, press
upload and the car should be up and running.
