Keyestudio KEYBOT Coding Robot Control Board


Description

The Keyestudio KEYBOT Coding Robot Control Board is particularly designed for car robot control.
This control board has integrated the UNO R3 control board and a motor drive board into one circuit board, which can directly drive two DC motors.
For the convenience of car design, this control board comes with a Bluetooth interface (fully compatible with HC-06 Bluetooth module), 2 servo interfaces and a passive buzzer. For easy car control, this control board also comes with 2 slide switches and a reset button. The large slide switch is used for an external power supply control. While the small switch is used for the serial port communication of Bluetooth module.
For simple connection, it extends all the digital and analog ports out as telephone sockets. It also comes with a power interface. The telephone socket integrates the digital and analog ports together, so you just need a cable to connect it with sensor modules, pretty simple and convenient.
We also provide you with 2pcs of acrylic plate, 4pcs of M3*15 double-pass copper pillars, 8pcs of M3*10 screws. You can use them to fix and protect your control board.

Detailed Use with ARDUINO Software as follows:

Step1 | Download the Arduino environment (IDE)

When you get the UNO development board, first you should install the Arduino software and driver.
We usually use the Windows software Arduino 1.5.6 version. You can download it from the link below:
https://www.arduino.cc/en/Main/OldSoftwareReleases#1.5.x
Or you can browse the ARDUINO website to download the latest version from this link, https://www.arduino.cc, pop up the following interface.
KS0313-1.png

Then click the SOFTWARE on the browse bar, you will have two options ONLINE TOOLS and DOWNLOADS.
KS0313-2.png

Click DOWNLOADS, it will appear the latest software version of ARDUINO 1.8.5 shown as below.
KS0313-3.png

In this software page, on the right side you can see the version of development software for different operating systems. ARDUINO has a powerful compatibility. You should download the software that is compatible with the operating system of your computer.
We will take WINDOWS system as an example here. There are also two options under Windows system, one is installed version, the other is non-installed version. For simple installed version, first click Windows Installer, you will get the following page.

KS0313-5.png

This way you just need to click JUST DOWNLOAD, then click the downloaded file to install it.
For non-installed version, first click Windows ZIP file, you will also get the pop-up interface as the above figure.
Click JUST DOWNLOAD, and when the ZIP file is downloaded well to your computer, you can directly unzip the file and click the icon of ARDUINO software to start it.


Installing Arduino (Windows)

Install Arduino with the exe. Installation package downloaded well.
thumb

Click“I Agree”to see the following interface.

Click “Next”. Pop up the interface below.
thumb

You can press Browse… to choose an installation path or directly type in the directory you want.
Then click “Install” to initiate installation.
thumb

Wait for the installing process, if appear the interface of Window Security, just continue to click Install to finish the installation.

Installing Driver

The driver installation may have slight differences in different computer systems. So in the following let’s move on to the driver installation in the WIN 7 system.
The Arduino folder contains both the Arduino program itself and the drivers that allow the Arduino to be connected to your computer by a USB cable. Before we launch the Arduino software, you are going to install the USB drivers.

KS0001-1.jpg

Plug one end of your USB cable into the KEYBOT Coding Robot Control Board, and the other into a USB socket on your computer. When you connect KEYBOT Coding Robot Control Board to your computer at the first time, right click the icon of your “Computer” —>for “Properties”—> click the “Device manager”, under “Other Devices”, you should see an icon for “Unknown device” with a little yellow warning triangle next to it.
Driver 1.png
Then right-click on the device and select the top menu option (Update Driver Software...) shown as the figure below.
Driver 2.png

It will then be prompted to either “Search Automatically for updated driversoftware” or “Browse my computer for driver software”. Shown as below. In this page, select “Browse my computer for driver software”.
Driver 3.png

After that, select the option to browseand navigate to the “drivers” folder.
Driver 4.png

Click “Next” and you may get a security warning, if so, allow the software to be installed. Shown as below.
Driver 5.png

Once the software has been installed, you will get a confirmation message. Installation completed, click “Close”.
Driver 6.png

Up to now, the driver is installed well. Then you can right click “Computer” —>“Properties”—>“Device manager”, you should see the device as the figure shown below.

Step2| Driving Two DC Motors

Below is an example code, you can copy and paste it on Arduino IDE.

const int PWMA = 5;  // define the left motor speed control of pin D5
const int PWMB = 6;  // define the right motor speed control of pin D6 
const int INT_A = 4;  // define the left motor control of pin D4 
const int INT_B = 7;  // define the right motor control of pin D7  
void setup() 
{  
   pinMode(PWMA,OUTPUT);  // set the pin of motor control as output
   pinMode(PWMB,OUTPUT);
   pinMode(INT_A,OUTPUT);
   pinMode(INT_B,OUTPUT);
}
void loop() 
{
  digitalWrite(INT_A,HIGH);  // the left motor rotates forward
  digitalWrite(INT_B,HIGH);   // the right motor rotates forward
  analogWrite(PWMA,200);   // the speed of left motor(PWM=200)
  analogWrite(PWMB,200);   // the speed of right motor(PWM=200)
  delay(2000);
  analogWrite(PWMA,0);   // the speed of left motor(PWM=0)
  analogWrite(PWMB,0);   // the speed of right motor(PWM=0)
  delay(2000);
  digitalWrite(INT_A,LOW);   // the left motor rotates backward
  digitalWrite(INT_B,LOW);  // the right motor rotates backward
  analogWrite(PWMA,200);   // the speed of left motor(PWM=200)
  analogWrite(PWMB,200);   // the speed of right motor(PWM=200)
  delay(2000);
}


Step3| Upload the Code

Open the Arduino IDE, you’ll need to click the “Tools”, then select the Board that corresponds to your Arduino and the serial port.
Ks0350-图片1.png

Then click the compile button, if compiling successfully, the message "Done compiling." will appear in the status bar. Shown below.
Ks0350-图片2.png

After that, click the “Upload” button, if the upload is successful, the message "Done uploading." will appear in the status bar.
Ks0350-图片3.png


Step4| What You Should See

Done uploading, connect two DC motors to the control board, then supply DC 7-12V power for the control board. Turn on the large slide switch, you should see the two motors rotate forward for 2 seconds, stop 2 seconds then backward for 2 seconds, circularly.
