Why use Arduino?

• Arduino is a very popular single board microcontroller,hence very low cost. (~$8)

• Open source, anyone can duplicate, royalty free.

• Easy to understand software environment (IDE).

• Lots of primitives built in, little initialization.

• www.arduino.cc website has lots of support

• Hardware is easy to use, lots of documentation

• Microchip-ATMEGA328 at Digikey

• Many, ready made daughter cards, (Shields).

Arduino UARTThe following code will make Arduino send hello world when it starts up.void setup() {Serial.begin(9600); //set up serial library baud rate to 9600Serial.println("hello world"); //print hello world}void loop() { }After the Arduino sketch has been uploaded to Arduino,open the Serial monitor at the top right section of Arduino IDE.Type anything into the top box of the Serial Monitor and press send or “Enter”.This will send a series of bytes to the Arduino.The following code returns whatever it receives as an input.

void setup() {Serial.begin(9600); //set up serial library baud rate to 9600}void loop() {if(Serial.available()) { //if number of bytes (characters) available for readingSerial.print("I received:"); //print I receivedSerial.write(Serial.read()); //send what you read } }Notice that Serial.print and Serial.println will send back the actual ASCII code,whereas Serial.write will send back the actual text.
