What is an Arduino ?

4.
The Arduino is an …
single-board microcontroller, intended to make the application of interactive
objects or environments more accessible .
Designed to make the process of using electronics multidisciplinary projects
more accesible

5.
Arduino can…
Sense the environment by receiving input from variety of sensors.
Affect its surroundings by controlling lights, motors, and other actuators.

6.
Brief History of Arduino
In 2005, a project was initiated to make a device for controlling student-built interactive design
projects that was less expensive than other prototyping systems available at the time.
Founders Massimo Banzi and David Cuartielles named the project after Arduin of Ivrea and
began producing boards in a small factory located in Ivrea.

7.
Programming Environment
The Arduino Uno can be programmed with the Arduino software IDE(integrated
development environment) .
The Atmega328 on the Arduino Uno comes preburned with a Bootloader that allows you
to upload new code to it without the use of an external hardware programmer.
You can also bypass the Bootloader and program the microcontroller through the ICSP
(In-Circuit Serial Programming) header.
Arduino IDE works on windows , linux as well as Mac lion X platforms.

What is a Microcontroller
• A small computer on a single chip
• containing a processor, memory,
and input/output
• Typically "embedded" inside some
device that they control
• A microcontroller is often small and low
cost

18.
What is a Development
Board
A printed circuit board designed to
facilitate work with a particular
microcontroller.
• Typical components include:
• power circuit
• programming interface
• basic input; usually buttons and
LEDs
• I/O pins

Getting Started
Check out: http://arduino.cc/en/Guide/HomePage
1. Download & install the Arduino environment (IDE)
2. Connect the board to your computer via the UBS cable
3. If needed, install the drivers (not needed in lab)
4. Launch the Arduino IDE
5. Select your board
6. Select your serial port
7. Open the blink example
8. Upload the program

• File > Examples > Digital > Blink
• LED’s have polarity
– Negative indicated by flat side of the housing
and a short leg

28.
A Little Bit About
Programming
• Code is case sensitive
• Statements are commands
and must end with a semi-
colon
• Comments follow a // or
begin with /* and end with
*/

Terminology

31.
Digital I/0
pinMode(pin, mode)
Sets pin to either INPUT or OUTPUT
digitalRead(pin)
Reads HIGH or LOW from a pin
digitalWrite(pin, value)
Writes HIGH or LOW to a pin
Electronic stuff
Output pins can provide 40 mA of current
Writing HIGH to an input pin installs a 20KΩ pullup

32.
Arduino Timing
• delay(ms)
– Pauses for a few milliseconds
• delayMicroseconds(us)
– Pauses for a few microseconds

33.
