III. Fuctions of Usage Intstructions
Infrared Tracking Mode
①Adjust potentiom【SW3】to make photoelectric sensor【P3】against white undersurface, then
LED light【L3】illumiinates while against black surface, LED light【L3】goes off.
②Adjust potentiom【SW4】to make photoelectric sensor【P2】against white undersurface, then
LED light【L2】illumiinates while against black surface, LED light【L2】goes off.
Caution:Don’t excessively rotate potentiometer while adjusting. It should be within 30°.
Obstacle Avoidance Mode
①Adjust potentiometer【SW1】to make the infrared light-emitting diode【LEAS1】and infrared
light-receiving diode【RC1】away from obstacle less than 10cm, then LED light 【L4】illuminates,
otherwise, it goes off.
②Adjust potentiometer【SW2】to make the infrared light-emitting diode【LEAS2】and infrared
light-receiving diode【RC2】away from obstacle less than 10cm, then LED light 【L5】illuminates,
otherwise, it goes off.
Caution:Don’t excessively rotate potentiometer while adjusting. It should be within 30°.

2.Introdution
The Arduino Smart Car (Bluetooth Version) has a Bluetooth module added to the standard
configuration. Users can use the APP we provide to perform Bluetooth remote control. The
Bluetooth remote control includes controlling the car's front, rear, left and right travel, adjusting
the speed, and rotating. Smooth operation, good experience, suitable for users who need to play
with remote control cars. The current APP program only supports Android phones.
3. Bluetooth remote control instructions
①First, connect the car according to the Bluetooth experiment
wiring diagram P15.
②Turn on the smart car to ensure the power of the Bluetooth
module is normal (the light of the Bluetooth module is blinking)
③Open the Bluetooth of the mobile phone and find the
Bluetooth module device in the Bluetooth settings. Click to
enter the password: 1234.
④Open Bluetooth App, remote control interface
is as follows. If the Bluetooth function is not
enabled on the phone, the display button next to
the "Bluetooth switch" is dark. Click to open, as
shown in the photo
(Bluetooth can also be set in the mobile system)
⑤Click “Search”
⑥Click the drop-down button to select the physical address of the connected
Bluetooth module
⑦Click“connect”. You will be prompted after successful connection. If the connection fails, you
return to the first step to check and try to reconnect.
