What is arduino ?

Arduino is an open-source electronics prototyping platform based on flexible, easy-to use hardware and software. It’s intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments. Arduino can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators. The microcontroller on the board is programmed using the Arduino programming language and the Arduino Development Environment. Arduino projects can be stand-alone, or they can communicate with software running on a computer.

There are plenty of other microcontrollers available. So you may be asking, why choose the Arduino? Arduino really simplifies the process of building projects on a microcontroller making it a great platform for amateurs. You can easily start working on one with no previous electronics experience.

In addition to Arduino’s simplicity, it is also inexpensive, cross-platform and open source. The Arduino is based on Atmel’s ATMEGA328 and ATMEGA168 microcontrollers.

Arduino Software

Software programs, called sketches, are created on a computer using the Arduino integrated development environment (IDE). The IDE enables you to write and edit code and convert this code into instructions that Arduino hardware understands.
The IDE also transfers those instructions to the Arduino board (a process called uploading).

Arduino Hardware

The Arduino board is where the code you write is executed. The board can only control and respond to electricity, so specific components are attached to it to enable it to interact with the real world. These components can be sensors, which convert some aspect of the physical world to electricity so that the board can sense it, or actuators, which get electricity from the board and convert it into something that changes the world. Examples of sensors include switches, accelerometers, and ultrasound distance sensors. Actuators are things like lights and LEDs, speakers, motors, and displays.

There have been a number of Arduino versions, all based on an 8-bit Atmel AVR reduced instruction set computer (RISC) microprocessor. The first board was based on the ATmega8 running at a clock speed of 16 MHz with 8 KB flash memory; later boards such as the Arduino NG plus and the Diecimila (Italian for 10,000) used the
ATmega168 with 16 KB flash memory. The most recent Arduino versions, Duemilanove and Uno, use the ATmega328 with 32 KB flash memory and can switch automatically between USB and DC power. For projects requiring more I/O and memory, there’s the Arduino Mega1280 with 128 KB memory or the more recent Arduino Mega2560 with 256 KB memory.
The boards have 14 digital pins, each of which can be set as either an input or output, and six analog inputs. In addition, six of the digital pins can be programmed to provide a pulse width modulation (PWM) analog output. A variety of communication protocols are available, including serial, serial peripheral interface bus (SPI), and I2C/ TWI. Included on each board as standard features are an in-circuit serial programming (ICSP) header and reset button.



Project 1: Creating a blinking LED wave

Let’s put some LEDs and resistors to work. In this project, we’ll use five LEDs to create a kind of wavelike light pattern.

The Hardware

Here’s what you’ll need to create this project:

>> Five LEDs
>> Five 560W resistors
>> One breadboard
>> Various connecting wires
>> Arduino and USB cable

We will connect the LEDs to digital pins 2 through 6 via the 560-ohm
current-limiting resistors.

The Sketch

Now for our sketch. Enter this code into the IDE:


// Project 1 - Creating a Blinking LED Wave

void setup()
{
pinMode(2, OUTPUT); // LED 1 control pin is set up as an output
pinMode(3, OUTPUT); // same for LED 2 to LED 5
pinMode(4, OUTPUT);
pinMode(5, OUTPUT);
pinMode(6, OUTPUT);
}
void loop()
{
digitalWrite(2, HIGH); // Turn LED 1 on
delay(500); // wait half a second
digitalWrite(2, LOW); // Turn LED 1 off
digitalWrite(3, HIGH); // and repeat for LED 2 to 5
delay(500);
digitalWrite(3, LOW);
digitalWrite(4, HIGH);
delay(500);
digitalWrite(4, LOW);
digitalWrite(5, HIGH);
delay(500);
digitalWrite(5, LOW);
digitalWrite(6, HIGH);
delay(500);
digitalWrite(6, LOW);
digitalWrite(5, HIGH);
delay(500);
digitalWrite(5, LOW);
digitalWrite(4, HIGH);
delay(500);
digitalWrite(4, LOW);
digitalWrite(3, HIGH);
delay(500);
digitalWrite(3, LOW);
// the loop() will now loop around and start from the top again
}



In void setup() the digital I/O pins are set to outputs, because we want them to send current to the LEDs on demand. We specify when to turn on each LED using the digitalWrite() function in the void loop() section of the sketch.

From what I'm seeing in your site it looks like you also provide PCB designs also?.
How about learning about device drivers for these OGBe so that it can be a general purpose device that can be progammable and interfacable with Computers.
