Keyestudio Frog Robot for Arduino Graphical Programming


About the tutorial

What an amazing Otto Frog Robot is coming!
This kit provides a perfect opportunity to build your very first robot, and it makes the process of learning about robotics easy, interactive, and FUN!
The kit is based on the keyestudio nano ch340, compatible with both Arduino open-source platform and Mixly Blocks coding.
You can program your own robot to walk, dance and follow obstacle, easy to build and code. No prior tech experience required!
Through play and experimentation children can exercise computational thinking and put skills into practice that are necessary for problem solving.


Features

  • Voltage input: DC 7-12V
  • Ultrasonic module for measuring the front obstacle distance, forming obstacle avoiding system;
  • Pairing HM-10 Bluetooth module with mobile Bluetooth to navigate the frog robot;
  • Providing the mobile APP compatible with both Android and mac system;
  • The NANO shield extends 12 digital pins and 8 analog pins into 3pin header, easy to connect a couple of sensor modules for projects extension;
  • The NANO shield comes with an I2C communication pin, able to connect I2C communication module for experiment extension.

2)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 robot projects, please click the link to get the basic understanding of Mixly software.

3)Import Robot Library

For the robot kit, we have developed keyestudio frog robot library.
Don’t forget to import the keyestudio OTTO_Frog robot library to Mixly software before coding the robot projects.
Must import the robot library first, or else you can’t check all the test code.


Ks0446图片9.png

Unzip the OTTO_Frog library package, you can see the OTTO_Frog_Robot XML.document.
Ks0446图片10.png

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.

Hardware Projects

As you work your way through each project, you will learn to how to program the robot to move, dance, and follow obstacles.

Project 1: Keyestudio NANO CH340

Keyestudio Nano ch340


Introduction:
keyestudio Nano CH340 is a small, complete, and breadboard-friendly board based on the ATmega328P-AU. Compared with ARDUINO NANO, the USB-to-serial port chip used in keyestudio Nano is CH340G, so that the using method is the same except the driver installation file.
It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 8 analog inputs, a 16 MHz crystal oscillator, a mini USB port, an ICSP header and a reset button.
Note that ICSP (In-Circuit Serial Programming) header is used to program the firmware to ATMEGA328P-AU, but generally the chip has been preburned before leave the factory. So use it less.
The keyestudio Nano can be powered via the Mini-B USB connection, or female headers Vin/GND (DC 7-12V).


TECH SPECS:

Microcontroller ATmega328P-AU
Operating Voltage 5V
Input Voltage (recommended) DC7-12V
Digital I/O Pins 14 (D0-D13) (of which 6 provide PWM output)
PWM Digital I/O Pins 6 (D3, D5, D6, D9, D10, D11)
Analog Input Pins 8 (A0-A7)
DC Current per I/O Pin 40 mA
Flash Memory 32 KB of which 2 KB used by bootloader
SRAM 2 KB
EEPROM 1 KB
Clock Speed 16 MHz
LED_BUILTIN D13


Element and Interfaces:
Here is an explanation of what every element and interface of the board does:

Specialized Functions of Some Pins:

  • Serial communication: 0 (RX) and 1 (TX). Used to receive (RX) and transmit (TX) TTL serial data.
  • PWM (Pulse-Width Modulation): D3, D5, D6, D9, D10, D11
  • External Interrupts: D2 (interrupt 0) and D3 (interrupt 1). These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value. See the attachInterrupt() function for details.
  • SPI communication: D10 (SS), D11 (MOSI), D12 (MISO), D13 (SCK).
  • IIC communication: A4 (SDA); A5(SCL)


Project 2: keyestudio NANO Shield

Keyestudio NANO Shield (Black and Eco-friendly)


Introduction:
keyestudio Nano ch340 is a tiny control board based on Arduino platform, which is deeply popular.
However, if want to connect several sensor modules to keyestudio Nano ch340, and connect external power, we need to use breadboard and a bunch of jumper wires, which is pretty inconvenient.
We specially design this NANO shield, fully compatible with keyestudio Nano ch340.

TheNANO shield has brought out digital and analog pins of keyestudio Nano ch340 into 3PIN headers (GND, 5V, Signal) with pin pitch of 2.54mm.
The NANO shield also leads out frequently-used communication pins, such as serial port communication and I2C communication. It’s greatly easy to connect keyestudio Nano ch340 and other sensor modules.
It comes with a power indicator and a reset button as well.
For external power, the NANO shield comes with a PH2.0-2P connector (input DC7-12V); a Power_Switch for power control.
To supply power for other sensors, the NANO shield comes with a 3-way DC3.3V power output pin header with pin pitch of 2.54mm.
It comes with 4 fixing holes with a diameter of 3mm, so easy to mount on other devices.


Features:

  • 1.Extends 12 digital pins into 3pin header
  • 2.Extends 8 analog pins into 3pin header
  • 3.Comes with a serial communication pin header (for Bluetooth module)
  • 4.Comes with an I2C communication pin
  • 5.Comes with 3-way DC 3.3V power output pin
  • 6.Comes with a power indicator and a reset button
  • 7.Comes with an external power connector(PH2.0-2P)and a control button
