…an open-source electronics platform based on easy-to-use

hardware and software.

• Eaaaaasy to use

• Inexpensive

• Cross-platform

• Simple, clear programming environment

• Open source and extensible software

• Open source and extensible hardware

Description

How to Use the Arduino• Write code in Arduino IDE.

• Connect Arduino to PC using USB cable.

• Click button on IDE to compile program.

• Click button on IDE to load program

unto microcontroller.

• Voila!

…any device that accepts input, performs some computations or

processing of the input and produces an output.

Technically, that makes an Arduino a computer.

Programming Language

Code Structure1    void  setup()  {  2  3    }  4  5    void  loop()  {  6  7    }

Sample Program 11    void  setup()  {  2        pinMode(13,  OUTPUT);  3    }  4  5    void  loop()  {  6        digitalWrite(13,  HIGH);  7        delay(1000);  8  9        digitalWrite(13,  LOW);  10      delay(1000);  11  }

Sample Program 21    void  setup()  {  2        pinMode(11,  OUTPUT);  3    }  4  5    void  loop()  {  6        for  (int  i=0;  i<255;  i++)  {  7            analogWrite(11,  i);          8            delay(500);  9        }  10  }

Programming Workflow2. Verify/compile code

3. Upload code unto microcontroller Converts wiring language to bytes of instructions in one Intel hex file. Loads hex file unto microcontroller

1. Write code
