This code summarizes an Arduino sketch that blinks an LED by turning it on for one second and off for one second repeatedly. It defines an integer variable 'led' set to pin 13, which is connected to an LED on most Arduino boards. In setup, it defines pin 13 as an output. The main loop turns the LED on by setting pin 13 high for one second, then off by setting it low for one second, repeating indefinitely.

Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so you use the Arduino programming language (based on Wiring), and the Arduino Software (IDE), based on Processing. Over the years Arduino has been the brain of thousands of projects, from everyday objects to complex scientific instruments. A worldwide community of makers - students, hobbyists, artists, programmers, and professionals - has gathered around this open-source platform, their contributions have added up to an incredible amount of accessible knowledge that can be of great help to novices and experts alike. Arduino was born at the Ivrea Interaction Design Institute as an easy tool for fast prototyping, aimed at students without a background in electronics and programming. As soon as it reached a wider community, the Arduino board started changing to adapt to new needs and challenges, differentiating its offer from simple 8-bit boards to products for IoT applications, wearable, 3D printing, and embedded environments. Why Arduino? Thanks to its simple and accessible user experience, Arduino has been used in thousands of different projects and applications. The Arduino software is easy-to-use for beginners, yet flexible enough for advanced users. It runs on Mac, Windows, and Linux. Teachers and students use it to build low cost scientific instruments, to prove chemistry and physics principles, or to get started with programming and robotics. Designers and architects build interactive prototypes, musicians and artists use it for installations and to experiment with new musical instruments. Makers, of course, use it to build many of the projects exhibited at the Maker Faire, for example. Arduino is a key tool to learn new things. Anyone - children, hobbyists, artists, programmers - can start tinkering just following the step by step instructions of a kit, or sharing ideas online with other members of the Arduino community. There are many other microcontrollers and microcontroller platforms available for physical computing. Parallax Basic Stamp, Netmedia's BX-24, Phidgets, MIT's Handyboard, and many others offer similar functionality. All of these tools take the messy details of microcontroller programming and wrap it up in an easy-to-use package. Arduino also simplifies the process of working with microcontrollers, but it offers some advantage for teachers, students, and interested amateurs over other systems: Inexpensive - Arduino boards are relatively inexpensive compared to other microcontroller platforms. The language can be expanded through C++ libraries, and people wanting to understand the technical details.

Arduino (/ɑːrˈdwiːnoʊ/) is an Italian open-source hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices. Its hardware products are licensed under a CC BY-SA license, while the software is licensed under the GNU Lesser General Public License (LGPL) or the GNU General Public License (GPL),[1] permitting the manufacture of Arduino boards and software distribution by anyone. Arduino boards are available commercially from the official website or through authorized distributors.[2] Arduino board designs use a variety of microprocessors and controllers. The boards are equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards ('shields') or breadboards (for prototyping) and other circuits. The boards feature serial communications interfaces, including Universal Serial Bus (USB) on some models, which are also used for loading programs. The microcontrollers can be programmed using the C and C++ programming languages (Embedded C), using a standard API which is also known as the Arduino Programming Language, inspired by the Processing language and used with a modified version of the Processing IDE. In addition to using traditional compiler toolchains, the Arduino project provides an integrated development environment (IDE) and a command line tool developed in Go.

Sound The Alarm ( PWM ) //PWM: 3, 5, 6, 9, 10, and 11. int ledPin = 9; int alarmPin = 10; void setup() { } void loop() { for(int fadeValue = 0 ; fadeValue <= 255; fadeValue +=20) { analogWrite(ledPin, fadeValue); analogWrite(alarmPin,fadeValue); delay(30); } for(int fadeValue = 255 ; fadeValue >= 0; fadeValue -=20) { analogWrite(ledPin, fadeValue); analogWrite(alarmPin,fadeValue); delay(30); } }

12. Make It Interactive int alarm = LOW; int val; void setup() { Serial.begin(9600); Serial.flush(); } void loop() { if(Serial.available()) { val = Serial.read(); Serial.println(val); if (val == 'A') alarm = HIGH; else alarm = LOW; } if (alarm) { Alarm(); } else { analogWrite(ledPin,0); analogWrite(alarmPin,0); } } import serial import time sp = '/dev/ttyACM0' ser = serial.Serial(sp,9600) seconds = 0.0 while seconds < 10: ser.write('A') time.sleep(.8) seconds += .8

13. Extra Step ●Install gnome-alarm ●set an alarm to 'Sound the Alarm !'
