# 2. Product setup
**Caution**: Peel thin films off boards before installing this robot. Note that the initial angle of the servo must be set during installation.

**Step1**
Tools needed:



**Note:** Pay attention to the installation direction of the wheels. The thick side should be on the outside.


**Step2**

The wheels and tracks must be installed. Then mount them on the car body simultaneously. Otherwise the tracks cannot be installed.


**Note:** Pay attention to where the wheels are mounted on the tracks.


**Step3**



**Note:** Please wire up first.





**Step 4**



**Step 5**



**Step 6**



**Step 7**

**Note:** Pay attention to the direction of jumper caps.


**Step 8**



**Step 9**



**Step 10**
(Need to adjust the angle of the servo)


**Set the angle of the servo to 90°**
To adjust the code of the servo, please select the corresponding code according to the course.
1.**Arduino:**Download the code file:[Arduino](./Arduino.7z)

2.**Kidsblock:**Download the code file:[Kidsblock](./Kidsblock.7z)

**After initializing servo angle, install the Bluetooth module.**
Keep the ultrasonic sensor parallel to the board.


**Step 11**



**Step 12**



**Wire up**
For the 8\*16 LED panel, connect the wires to A4 and A5.



Connect motor A to the A port and motor B to the B port.


Connect the power wire.
