2 SO What is an Arduino?

3 WELL!! Arduino is an open-source prototyping platform based on easy-to-use hardware and software.

4 Why Arduino? Simplifies working on a microcontroller Inexpensive Platform Simple, Clear and User Friendly Environment Easy Programming

5 MISSED SOMETHING? OPEN SOURCE!!

6 IMPORTING LIBRARY Open the Given Arduino Library Folder Copy the files to C:/Program Data/Labcenter Electronics/Proteus 8 Professional/Library/ Reopen Proteus and Use Arduino from Components Adding Panel NOTE : Program Data folder is Hidden

8 ARDUINO UNO DESCRIPTION 13 Pins, ~ PWM, 0&1: Rx & Tx ports USB Port SPI ( Serial Peripheral Interface) MISO MOSI Atmel ATmega 328 External Power Supply Analog Input Pins

9 Arduino IDE setup(){ // runs once at start of program // for initialization loop(){ // called repeatedly until board // powers off

10 Some Basic Programming Syntax In setup() pinmode( pinno, mode ); Mode : INPUT / OUTPUT Eg ; pinmode(13, OUTPUT); Serial.begin( baudrate ); baudrate : bits per second For Serial Communication Eg ; Serial.begin(9600);

11 Some Basic Programming Syntax In loop() digitalwrite ( pinno, state ); State : HIGH / LOW Eg ; digitalwrite (13, HIGH); digitalread ( pinno); Eg ; int value = digitalread(8); delay (milliseconds); Delays system by certain milliseconds Eg ; delay(1000); // for 1 sec

12 Some Basic Programming Syntax In loop() analogwrite ( pinno, value ); Value : 0 to 255 //(255/255) = 1 = max value Eg ; analogwrite (9, 255); // pinno with PWM analogread ( pinno); Eg ; int value = analogread (A0); Serial.println (data); Displays data on Serial Monitor with line break Eg ; Serial.println ( Text );
