workshop

Arduino is a single-board microcontroller to make using electronics in multidisciplinary projects more accessible. The hardware consists of an open-source hardware board designed around an 8-bit Atmel AVR microcontroller, or a 32-bit Atmel ARM. The software consists of a standard programming language compiler and a boot loader that executes on the microcontroller.
Arduino boards can be purchased pre-assembled or as do-it-yourself kits. Hardware design information is available for those who would like to assemble an Arduino by hand. It was estimated in mid-2011 that over 300,000 official Arduinos had been commercially produced.

The Arduino integrated development environment is a cross-platform application written in Java, and is derived from the IDE for the Processing programming language and the Wiring projects. It is designed to introduce programming to artists and other newcomers unfamiliar with software development. It includes a code editor with features such as syntax highlighting, brace matching, and automatic indentation, and is also capable of compiling and uploading programs to the board with a single click. A program or code written for Arduino is called a "sketch".
Arduino programs are written in C or C++. The Arduino IDE comes with a software library called "Wiring" from the original Wiring project, which makes many common input/output operations much easier. Users only need define two functions to make a runnable cyclic executive program:
setup(): a function run once at the start of a program that can initialize settings
loop(): a function called repeatedly until the board powers off
A typical first program for a microcontroller simply blinks an LED on and off.

Software

#define LED_PIN 13

void setup () {
pinMode (LED_PIN, OUTPUT); // Enable pin 13 for digital output
}

void loop () {
digitalWrite (LED_PIN, HIGH); // Turn on the LED
delay (1000); // Wait one second (1000 milliseconds)
digitalWrite (LED_PIN, LOW); // Turn off the LED
delay (1000); // Wait one second
}

In my work

In the workshop, we tried to fix Arduino with 'Blink'. In Blink, we sent the signals to Arduino for LED light response. Firstly, we connected one LED light that we required the LED light blink in one second.

Finally, we added potentiometer to the breadboard. Potentiometers are commonly used to control electrical devices. Potentiometers operated by a mechanism can be used as position transducers, for example, in a joystick.

We need to connect a breadboard with Arduino. Also, we needed cable and resistor. Using cable to connect the breadboard and 'GND' of Arduino.

Then we added one and two more LED light in the breadboard.
