# Assembly the Car

## Solder the motors

Solder each motor with a black and a red wire and attach them with the chassis.

## Attach the Motors

Attached the motors to the base of the car. Join the left side motor wires together as: **red wire --> red wire** and **black wire --> black wire,** similarly join the motors on right side together as: **red wire --> red wire** and **black wire --> black wire**

## Connect the Motor Driver

The Motor driver will be the **back** of the car. The Motor driver will have two connectors, one for Motor A and another for Motor B.

Looking at the car from behind, connect the **Left motors** to **Motor A** and the **Left motors** to **Motor B.**

Remember that the two left motors will connect to a single Motor A and two right Motors will connect to a single Motor B on the motor driver

Connect the jumper wires as below:

**Please remove the jumper from ENA and ENB on the motor driver**

* Motor driver ENA -> PIN 9 on Arduino Board
* Motor driver IN1 -> PIN 8 on Arduino Board
* Motor driver IN2 -> PIN 7 on Arduino Board
* Motor driver ENB -> PIN 3 on Arduino Board
* Motor driver IN3 -> PIN 5 on Arduino Board
* Motor driver IN4 -> PIN 4 on Arduino Board

Connect the battery pack **positive** wire to the **VCC / 12V** terminal of the motor driver

Connect the battery pack **negative** battery to the **GND** terminal of the motor driver

Connect a jumper from the **VSS / 12v** terminal on the motor board to the **VIN** on the Arduino board. Connect another jumper from the **GND** on the motor driver to **GND** on the Arduino board

## Connect the Bluetooth Module to Arduino

Connect the Bluetooth module as shown below

Now you are done with the car assembly. Next you need to upload the code to the Arduino board, download the App and test.
