3. Arduino IDE
What is the Arduino IDE (Integrated Development Environment)?
It’s an Open Source software platform for developing Arduino applications.
It has a simple text editor for typing in code for the Arduino application.
It allows the code to be uploaded to the Arduino.
It has a Serial Monitor for debug of code and displaying text messages on notebook and desktop computers screen or monitor.

6. What is a Sketch?
“Arduino team calls the embedded software of its computing platform a sketch because the device was created for artists interested in making their artwork or pieces interactive with the viewer or audience.”[1]
A little computer program
Software code to tell the Arduino what to
A variant C programming language

8. Let’s Blink an LED!

9. Blink Sketch
/* Blink Turns on an LED on for one second, then off for one second, repeatedly. This example code is in the public domain. */ // Pin 13 has an LED connected on most Arduino boards. // give it a name: int led = 13; // the setup routine runs once when you press reset: void setup() { // initialize the digital pin as an output. pinMode(led, OUTPUT); } // the loop routine runs over and over again forever: void loop() { digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level) delay(1000); // wait for a second digitalWrite(led, LOW); // turn the LED off by making the voltage LOW

// constants won't change; they're used here to
// set pin numbers:
const int buttonPin = 2; // the number of the pushbutton pin
const int ledPin = 12; // the number of the LED pin
const int ledPin13 = 13; // onboard LED
void setup() {
// initialize the LED pins as outputs:
pinMode(ledPin, OUTPUT);
pinMode(ledPin13, OUTPUT);
// initialize the pushbutton pin as an input:
pinMode(buttonPin, INPUT); }
void loop(){
// read the state of the pushbutton value:
int buttonStatus;
buttonStatus = digitalRead(buttonPin);
// check if the pushbutton is pressed
// if it is, the buttonStatus is HIGH:
if (buttonStatus == HIGH) {
// turn LED on:
digitalWrite(ledPin, HIGH);
// turn off onboard LED:
digitalWrite(ledPin13,LOW);
else {
// turn LED off:
digitalWrite(ledPin, LOW);
// turn on onboard LED:
digitalWrite(ledPin13, HIGH);
