You can purchases this car from Amazon.

Elegoo Smart Robot Car Kit

It comes with everything you need, including batteries, Codes and Library's.

Also Comes with a data disk with a step by step guide in the from of a PDF File.

Step 1: Assambly Motors

Step 2: Mount Motors to Bottom Base Plate

Remove the protective paper from the base plate.

Note how the motors are mounted. You may need to reassemble the motors so the aluminum block is in the right spot.

You do not need to fully tighten the motors now. Just tighten enough so they stay on. You will need to adjust them later after you install the wheels.

Step 3: Install the Motor Driver Board

Pay attention to the direction of the motor driver board and the wiring.

Do not over tighten this board. You may damage it!

Step 4: Install the Line Tracking Module.

Step 5: Install the Arduino Uno R3 and the Extension Board

Install the Arduino Uno R3 and the Extension board on the top base plate.

Do not over tighten the Arduino Uno R3 board you may damage it.

Step 6: Install the IR Reciver and the Battery Case.

Do Not over tighten the IR receiver board.

My IR receiver doesn't sit flat after I tightened the screws. I bent the IR receiver a little so it pointed up move. Be careful you do not short it out if you bend it.

Do not over tighten the battery case.

Step 7: Install the Servo With the Ultrasonic Sensor

Be careful inserting the servo into the mounting plate and the base plate. Its a tight fit and you don't want to damage the wiring.

Do not over tighten the ultrasonic sensor you may damage it.

Plug the servo in to the digital 3 pin as shown.

You will connect the ultrasonic sensor later.

Step 8: Install the Copper Cylinders and Wire Up the Rest of the Motor Driver Board.

Install the copper cylinders on the bottom base plate.

Install the power from the batter case to the motor driver board.

Install 6 wires to control the board.

The six wires then fit through a hole on the top base plate.

You now can add the screws for the top base plate to the copper cylinders. I only installed two in case I had to take it back apart.

Connect all six wires to the expansion board

digital pins 5, 6, 7, 8, 9, 10.

Step 9: Wire Up the Line Tracking Modules.

Sensor one connects to digital 11

sensor two connects to digital 4

Sensor three connects to digital 2

Step 10: Wire Up the IR Receiver.

IR receiver connects to digital pin 12.

Step 11: Wire Up the Ultrasonic Sensor.

GND to Ground

Echo to A4

Trig to A4

VCC to +5VDC

Step 12: Install Blu Tooth and Finish Installing Screws to Copper Cylinders.

Blu tooth Extension board.

RXD to TX

TXD to RX

GND to - (Ground)

VCC to + (+5VDC)

If you haven't already installed all the screws to hold the top and bottom base plates to geather you can now install them and tighten them.

Step 13: Install Wheels.

Install the wheels. You may need to or want to glue them on. Mine kept falling off. I use some Cement for Plastic Models.

After you install the wheels make them as straight as possible and tighten the screws holding the motors the the bottom base plate.

Step 14: Its Complete and Ready to Upload Some Codes!

The car comes with the following codes...

Lesson 1 Make Car Move

  • Auto Go
  • Forward Back
  • Left Wheel Rotation
  • Right Wheel Rotation

Lesson 2 Bluetooth Car

  • Bluetooth Blink
  • Bluetooth Car

Lesson 3 Infrared Remote Control Car

  • Infrared Blink
  • Infrared Remote Control Car

Lesson 4 Obstacle Avoidance Car

Lesson 5 Line Tracking Car

Step 15: Modification.

I added lights that I can control with the blutooth code.

Note adding more lights or other parts that consume electricity will shorten the run time.

Step 16: Furture...

I have been thinking about added the Raspberry Pi and a camera to stream video back to my android tablet.

with a pan and tilt camera mount.

I also am thinking about adding a Arduino Mega with a GPS module. So I can set a detestation point and have the car drive there by its self avoiding obstacles.

<p>My son and I just put this together. However, when we run the Auto Go program, the wheels run in opposite directions, i.e. the front try to go forward while the rear try to go backward. I'm trying to understand the motor wiring. If the motors on one side of the car (aligned in parallel) are opposite each other (back to back), but share the same positive and negative terminals (as pictured everywhere), then I would expect them to run in opposite directions when getting power from either ENA or ENB. Additionally, the program shows reversed values for in1 through in4, and ENA and ENB, than what the instructions have.(i.e. 9,8,7,6,10 and 5, respectively). Any thoughts? Is there a top and bottom to the motor and we may have them flipped? All of the wires are on the inside with the vertical slits (on the white parts) are all on the inside.</p>
<p>I had the same problem, Just flip them around so they turn in the same direction. when car is moving forward. </p>
<p>What did you flip, the motors or the wires?</p>
<p>I swapped wires and that worked.</p>
<p>The motors not the wires. </p>
So I'm getting some conflicting directions from you say and what the directions that came with it say, and even the directions that came with it conflict with each other, can I assume that you got this working so it should be considered completely correct?
<p>What seems to be the problem and yes Mine ran fine. </p>
Just where each wire goes on the top board, the included directions aren't clear and even show some in different places in other pictures
<p>I don't recall having trouble connecting the wires. Just make sure you connect the +5vcc and ground correctly before powering up so you don't fry anything. You can also look at the codes also to see what pins are defined for what. </p>
<p>I got the same kit but without the 2 batteries due to shipping restriction. So I connected a 9v battery instead and had a separate power source for the Arduino. However the wheels didn't move smoothly they kept stopping, so I added another set of 4 1.5v batteries (so now it should be a total of 18v powering the motors). but still with no luck, the wheels would run fine in the air but then put on the ceramic floor the car struggle to move and stops! Appreciate your advice of how much voltage needed to run this car kit</p>
<p>Mine came with 2 x 3.7V 4200mAh BRC18650 cells, if that helps.</p>
<p>Howdid you add the codes</p>
<p>where did you connect the LEDs? I would like to add this feature too but not sure wht pins to connect them to</p>
<p>I connected the LED's left over digital pins. As for the 12V led I wrote one pin LOW to turn it on and connected the positive to the battery box. </p>
