Description:

OSOYOO 2WD Robot Car Starter Kit is designed for beginners to learn Arduino programming and get hands-on experience on robot design and assembly.

We have developed a step-by-step tutorial which evolves from a simple car without any control to a multi-function robotic car controlled by mobile APP.

Every lesson has detailed sample code with comments, circuit graph, assembly instruction and video. Even if you have no programming experience, you can follow the step-by-step instruction and gradually become a master.

Our robotic car is 100% open source. If you are an intermediate player and have time to read our code comments, you can easily customize this robotic car to make your own project for science fair, college home work or even commercial applications.

This kit contains module parts including OSOYOO MODEL-X motor driver module(*), Tracking module, Infrared Remote Control and Sensor Shield V5.0 for Arduino UNO, etc. With these modules, the robot car can work in multiple modes such as auto-go, infrared control and line tracking. You can use our Android APP to change working mode through Bluetooth.

*OSOYOO MODEL X motor driver module is an improved L298N module which has newly designed wiring sockets and can greatly simplify the assembly procedure and wire connection stability.

Step 16: Its Complete and Ready to Upload Some Codes!

Now hardware installation is almost done. Before we install 18650 batteries into the box, we need burn the sample code into Arduino first.

Step 17: Install Latest Arduino IDE

Download Arduino IDE from https://www.arduino.cc/en/Main/Software?setlang=en, then install the software.

(If you have Arduino IDE version after 1.1.16, you can skip this step.)

Step 18: Download Sample Code

1. Check the Wire Connection: lesson-1.zip

2. IR Control: lesson-2.zip

IRremote library

3. Line Tracking: lesson-3.zip

4. Bluetooth Control: lesson-4.zip

Step 19: Open Arduino IDE, Choose Corresponding Board/port

Connect UNO R3 board to PC with USB cable, open Arduino IDE, choose corresponding board/port for your project

Step 20: Install IRremote Library Into Arduino IDE

Notice: If you want to use IR remote to control the car, you should Install IRremote.zip library Into Arduino IDE first, and then upload lesson-2.zip

Open Arduino IDE, install IRremote library into Arduino IDE (If you have already installed IRremote library, please skip this step)

Download IRremote.zip library, then import the library into Arduino IDE(Open Arduino IDE-> click Sketch->Include Library->Add .Zip Library)

Step 21: Upload the Sketch

Click file -> click Open -> choose code “lesson-1.ino”, load the code into Arduino, and then upload the sketch to the board.

Step 22: Check the Wire Connection

Disconnect Arduino from PC, put 2 fully-charged 18650 battery into battery pox(check the box instruction and make sure polar direction is correct, otherwise it can destroy your device and cause fire hazard).

Please install your battery as per picture instruction

Put the car on the ground, open the power switch in the battery box, the car should go forward 2 seconds, then go backward 2 seconds, then left turn for 2 seconds, then right turn for 2 seconds, then stop.

If the car does not move as per above mentioned result, you should check your wire connection, battery voltage(must over 7.2v).

Step 23: IR Control

Press IR controller keys to control the car movements:

∧: Forward

∨: Backward

＜: Turn left

＞: Turn right

If the car can’t move, please check the following:

If the battery can work;

If the IR controller is too far away from the receiver;

If the connection is right.

Step 24: Line Tracking

1: Prepare a black track on white ground. (the width of the black track is more than 20mm and less than 30mm)

Please note, the bend angle of the track can’t be larger than 90 degree. If the angle is too large, the car will move out of the track.

2: Adjust the sensitivity of tracking sensor modules.

Turn on and hold the car to adjust the potentiometer on the tracking sensor with Phillips screwdriver until you

get the best sensitivity status: the signal indicate LED light will turn on when sensor is above white ground, and

the signal LED will turn off when the sensor is above black track.

Signal Indicate LED ON: White Ground

Signal Indicate LED OFF: Black Track

3: Turn on the car and put the car over the black track, then the car will move along the black track.

Use the IR controller, press “OK”, the car will along the track; press “0”, the car will stop.

If the car can’t move, please check the following:

If the battery can work;

If the IR controller is too far away from the receiver;

If the connection is right;

If adjusted well the sensibility of the tracking sensor.

Step 25: Install the Bluetooth Module

Notice: If you want to control the car by Bluetooth, you should upload sample code lesson-4.zip into Arduino IDE first, then install the bluetooth module.

Install the bluetooth module on the Sensor Shield V5.0 for Arduino UNO:

Bluetooth Module ---- Sensor Shield V5.0 for Arduino UNO

RXD -- TX

TXD -- RX

GND -- -

VCC -- +

Step 26: Download Android APP

Download APP from: http://osoyoo.com/driver/car.apk

Or scan the following QR code with Android mobile phone to download the app

Step 27: Install Android APP

Step 28: Turn on Bluetooth of Your Android Phone

Please turn on bluetooth of your Android phone which you have installed APP and scan bluetooth (different bluetooth module will scan different bluetooth name), click connect and enter password “1234” or “0000” if no change

Step 29: Control Car by Android APP

Open app>> select bluetooth mode>> then you can controller the robot car through bluetooth:

Step 30: Bluetooth Control

There are two working mode: manual control and tracking. Users can switch freely among two working mode.

1) Manual Control Mode

In manual control mode, you can click buttons (∧) (∨) (＜) (＞) to control the Robot car to move forward and backward, turn left and turn right. Meanwhile, the APP can observe the car real time movement.

2) Tracking Mode

Click “tracking” button of App to switch the current mode to tracking mode. The Robot car will move forward along the black line in white background. Meanwhile, the APP can observe the car real time movement. Press “||” button to stop moving and click other button to change Robot car working mode.

The rest of the buttons are for the reservation function, you can develop them by yourself.
