Using the serial monitor that is built into the Arduino IDE (Integrated Development Environment, aka desktop software), write a program that reads in a value and echoes back the same value.

He's also open to sharing the firmware and software, though you'll need to contact him directly to access them. This proof of concept shows just how versatile the Arduino controller is.

To make things easy for the common user, he wrote a library called EasyTransfer which abstracts packetized serial communications between two Arduino boards.

So let’s say your using an Arduino in your project. You already have the hardware-based serial interface working with one portion of the project and need a second serial port for unrelated ha… ...

The Arduino is an open-source electronics prototyping platform composed of two major parts: the Arduino board (hardware) and the Arduino IDE (software). The Arduino IDE is used to write the program ...

For those starting out in Arduino, there are tons of resources to get better acquainted with the community and the types of projects you can tinker with.

Despite the professional deficiencies in the software platform, though, the use of the Arduino shields and hardware environments offer a great opportunity to help accelerate development through the ...

Connecting Arduino to Processing Introduction So, you’ve blinked some LEDs with Arduino, and maybe you’ve even drawn some pretty pictures with Processing - what’s next? At this point you may ...

So just like with open source software, people can and do make derivatives of Arduino boards or entirely new products powered by Arduino technology. Why is openness important in hardware? "Because ...

Official Arduino Example Tutorials: The Arduino computer software is loaded with tons of examples for you to use in your own code or to run through as a learning experience.
