Description

We can often see others on the internet making use of control boards and electrical components to build their own creative robots. Wanna DIY your own robot?

Here comes OpenELAB desktop mini Bluetooth smart car V3.0, which is an upgraded version of OpenELAB desktop mini Bluetooth smart car V2.0.

The smart car still keeps the functions like line tracking, obstacle avoidance, IR and Bluetooth control and more.

Furthermore, we make a great improvement for the smart car as follows:

1. The Acrylic plates are more bright and colorful;

2. Adding a microphone sound module to make a fantastic sound when driving the car running;

3. Using Bluetooth HM-10 module,which can support Bluetooth 4.0; supporting both Android and iOS system; also can actuate the smart car with our own designed Bluetooth APP.

4. Can freely choose the battery case 18650 or 4-cell AA battery case to supply power for the robot car. Note that batteries are Not Included. Users can freely choose two 18650 batteries or four AA batteries (1.5V) to supply power for the robot car.

5. Making improvements on the motor drive board; one is coming with a slide switch for controlling the power switch;the other is adding 8 jumper caps to control the DC motor direction by hand,easy for code debugging.

6. Coding the robot car with Mixly blocks software, more simple and ready to play.

From the basics up to complex projects, through this kit you can learn to control the robot car with Mixly blocks coding. Easy to code and learn coding and computational thinking.

If you are looking for inspiration, you can find a great variety of tutorials here. Take your brain on a fun and inspiring journey through the world of programming and electronics.

Parameters

1. Motor Voltage range: 1-6V; motor shaft length: 10mm; speed: 6.0V 100rpm/min.

2. Motor control is driven by L298P;

3. Three groups of line tracking modules, to detect black-white line with higher accuracy and can also be used for anti-fall control;

4. Two groups of obstacle detector modules, to detect whether there are obstacles on the left or right side of smart car; Ultrasonic module is used to detect the distance between ultrasonic and obstacles, forming the smart car’s obstacle avoidance system;

5. Bluetooth wireless module can be paired with Bluetooth device on mobile phone to remotely control smart car;

6. Infrared receiver module is matched with an infrared remote control to control the smart car;

7. Can access the external 7 ~ 12V voltage.

Component List

When get this smart car kit, at first glance, you will see the beautiful packaging box. And each component is safely packed inside the small bag in order. You will get such a bulk of components and screws to make your own smart car. So we have listed all the components as follows:

Getting Started With Mixly Software

Installing Arduino IDE

When program the UNO R3 development board, you can download the Arduino integrated development environment from the link: https://www.arduino.cc/en/Main/OldSoftwareReleases#1.5.x

Introduction for Mixly Blocks

Mixly is a free open-source graphical Arduino programming software, based on Google’s Blockly graphical programming framework, and developed by Mixly Team@BNU.

It is a free open-source graphical programming tool for creative electronic development; a complete support ecosystem for creative e-education; a stage for maker educators to realize their dreams.

More info please check the link to download the Mixly blocks software.

Before starting the below projects, please click the link to get the basic understanding of Mixly software.

Importing Robot Library

For the robot kit, we have developed OpenELAB robot car library. Don’t forget to import the OpenELAB desktop car library to Mixly software before coding the robot projects.

Must import the robot car library first, or else you can’t check all the test code.

Unzip the desktop_car library package, you can see the desktop_car XML.document.

Then import this document into Mixly library. Import custom library successfully!

You are able to click “Manager” to manage all imported libraries. Note: sometimes it may exists a conflict between libraries, so should keep only correct car library when using and delete other library.

Basic Projects

Project 1: UNO R3 Built-in LED

Introduction

The UNO R3 development board is the most popular one in Arduino board series. In addition, it is also the best choice for beginners to learn to build electronic circuits and write the source code.

If this is your first experience tinkering with the platform, the UNO R3 is the most robust board you can start playing with.

Let's take a look at the details of this development board with the following chart:

Let’s make a simple test for the UNO R3 built-in LED (D13).

It’s pretty simple to turn a built-in led on and off. We only require UNO R3 control board and a USB cable to enter the wonderful programming world.

Connect your UNO R3 board to the computer’s USB port using a USB cable for communication.

Test Code

Open Mixly blocks platform to get started with coding.

First, click IN/OUT, drag the “DigitalWrite PIN# (0)Stat(HIGH)” block.

This block is used to set the level HIGH or LOW of Digital pin.

Select HIGH is to set the HIGH level.

Select LOW is to set the LOW level.

The HIGH level is the state of high voltage, generally recorded as 1.

High voltage, high current, the LED lights. The LOW level is the state of low voltage, generally recorded as 0. Low voltage, low current, the LED Not lights.

To observe the LED blink obviously, we need to add a Delay block.

Check the test code below and upload it to your UNO R3 board.

Result

Drag the test code to Mixly window; remember to select the proper board and COM port. Then compile and upload the code to your control board. Upload success message will appear on the bottom bar.

The UNO R3 built-in LED (label “L”) will turn on for 1 second, and then turn off for 1 second, alternately and circularly.
