Build Your Own Arduino-controlled Robot (Code Provided):

Robotics can be a difficult hobby to jump into, but the Arduino and the 4WD Robot Platform make it easy for you to build an awesome robot without a struggle! By utilizing some Arduino components, this combo makes it easy for you to learn the basics of robotics, applications of the Arduino, and the process of building something awesome to show your family and friends. This can also be a fun toy!


This combo encourages creative thinking, if you are good at programming,you can make it a remote-controlled car or an autonomous robot by adding some sensors or webcam at your favor!

In addition to all the features of the previous board, the MEGA now uses an ATMega16U2 instead of the ATMega8U2 chip. This allows for faster transfer rates and more memory. No drivers needed for Linux or Mac (inf file for Windows is needed and included in the Arduino IDE), and the ability to have the Uno show up as a keyboard, mouse, joystick, etc.
  • 1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board. In future, shields will be compatible both with the board that use the AVR, which operate with 5V and with the Arduino Due that operate with 3.3V. The second one is a not connected pin, that is reserved for future purposes.
  • Stronger RESET circuit.
  • Atmega 16U2 replace the 8U2.
