What is Arduino?

Multi Sensory Communication 22

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.

Multi Sensory Communication 23

Arduino

• Arduino Board– ATMega328– USB– Open Source

• Arduino IDE(Integrated Development Environment)– Windows, Linux, Mac OSX– Opern Source– Based on Processing

• Arudino Programming language– Based on Wiring

Basis of Electrical Circuit

Multi Sensory Communication 44

Basic Knowledge

• Voltage – The difference in electric potential between

two points.– Unit symbol V(Volt)

• Electric current – A flow of electric charge through a medium.– Unit symbol A(Ampere)

• Resistance – The opposition to the passage of an electric

current.– Unit symbol Ω(Ohm)

Arduino Digital Pin

Control using servo library

Methods see… http://www.arduino.cc/en/Reference/Servo– attach(pin/number)

• Attach the Servo variable to a pin– write(angle/degrees 0 - 180)– writeMicroseconds(time/micro seconds1250 - 1750)– read(pin/number)

• The angle of the servo, from 0 to 180 degrees. – attached()

• Use as ServoObject.attached() returns true/false – detach()

• Use as ServoObject.detach() detach pin from servo
