Introduction

Nowadays, technological education such as VR, kids programming, and artificial intelligence, has become mainstream in educational industry. Thereby, people attach importance to STEAM education. Arduino is pretty notable in Maker education.

So what is Arduino? Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. Based on this, Keyestudio team has designed a 4wd robot. It has a processor which is programmable using the Arduino IDE, to mapped its pins to sensors and actuators by a shield that plug in the processor, it reads sensors and controls the actuators and decides how to operate.

15 learning projects, from simple to complex, will guide you how to make a smart 4wd robot on you own and introduce the detailed knowledge about sensors and modules.

Simultaneously, it is the best choice if you intend to obtain a DIY robot for learning programming, entertainment and competition requirement.

Note: The experiment you did should be in line with wiring diagram, including about components and wiring method. For example, we supply power with external power in the hook-up diagram, so you also have to use external power rather than USB cable.

Product List

Please tear off the protective film on the acrylic board before mounting the kit

Assembly Guide

Note: Peel the plastic film off the board first when installing the smart car. To be honest, we never intend to send wood to you.

Note: Remove the Bluetooth module before uploading test code, otherwise, you will fail to upload test code

Install Mixly Software and Driver

(1)Download and Install Mixly

①Description

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 complete support ecosystem for creative e-education, a stage for maker educators to realize their dreams.
② Download Mixly1.0
Windows System：https://fs.keyestudio.com/Mixly1-Windows
MACOS System：https://fs.keyestudio.com/Mixly1-MACOS

We will take Mixly1.0 (Windows version) as example, and the installation method of MAC version is similar with it.
You will get installation package after downloading. As shown below:

Unzip the package, you will see “Mixly 1.0 for keyestudio.exe”

Double-click ”Mixly 1.0 for keyestudio.exe”, the following interface pops up.

We have to choose correct Arduino development board and name, as shown below:

Select correct COM port(the corresponding port will be shown after installing driver successfully)

You have to know the function of every area and interface on Mixly software before uploading program on Arduino development board

Keyestudio V4.0 Development Board

We need to know keyestudio V4.0 development board, as a core of this smart car.

keyestudio V4.0 development board is an Arduino uno-compatible board, which is based on ATmega328P MCU, and with a cp2102 Chip as a UART-to-USB converter.

It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, 2 ICSP headers and a reset button.

It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it via an external DC power jack (DC 7-12V) or via female headers Vin/ GND(DC 7-12V) to get started.

Installing V4.0 board Driver

Let’s install the driver of keyestudio V4.0 board. The USB-TTL chip on V4.0 board adopts CP2102 serial chip. The driver program of this chip is included in Arduino 1.8 version and above, which is convenient. Plug on USB port of board, the computer can recognize the hardware and automatically install the driver of CP2102.

If install unsuccessfully, or you intend to install manually, open the device manager of computer. Right click Computer----- Properties----- Device Manager

There is a yellow exclamation mark on the page, which implies installing unsuccessfully. Then we double click the hardware and update the driver.

Click “OK” to enter the following page, click “browse my computer for updated driver software”, find out the installed or downloaded ARDUINO software. As shown below:

We click “Browse”, then find out the driver folder, or you could enter “driver” to search in rectangular box, then click “next”, the driver will be installed successfully. (I place Arduino software folder on the desktop, you could follow my way)
