Few years ago when the programming was quite difficult,only professionals and highly experienced people were able to write the program for the computer and machines. Nowadays many more complex systems are created and their complexity is increasing day by day but somehow we can analyze and relate those concept, thanks to the technology in education which enhances learning skills and makes learning an effective learning and the technology which are easy to operate and have the similar functionalities like complex systems.


An Arduino is an example of the technology which gives you hands on experience with hardware as well the software program to operate the hardware.If you are a beginner/enthusiast in embedded systems and robotics

,if you want to explore how thing works and how to make thing work Arduino is a perfect board to start with.


Arduino company have a wide varieties of boards designed to perform different tasks based on your requirement.From an arduino which you can stitch to your cloth to a wi-fi enabled arduino everything is available to make projects like turn signal indication t-shirt to control your home appliances from anywhere in the world where internet connectivity is available. Every board have specific GPIO pins.You can attach input devices like a sensor to collect the data and output devices like motor/actuator to react on that data.


Lets get Started with Arduino .

                                                     Image:Arduino Uno

                                Arduino Uno is a flagship board of Arduino Company.

 Technical Specifications:-

  • Microcontroller – Atmega328
  • Operating Voltage – 5volts
  • Input Voltage – 7v-12v(recommended)
  • Analog Input Pins – 6 pins
  • Digital I/O Pins – 14(6 PWM pins)
  • Power Out Pins – 3v,5v


Let us work with Arduino using a simple experiment to Blink two led’s consecutively with the help of digital pins.

Components Required:-

  1. Arduino Uno
  2. Usb Cable for Arduino
  3. 5 Male to Male Jumper Wires
  4. Breadboard
  5. 2 Led’s
  6. Laptop/PC with Arduino IDE installed

Connections:  +ve Led1->pin no.5


+ve Led2->pin no.6

-ve Led2->Ground

Resistors are not necessary, you can make the circuit without resistors. In case if you want to connect a resistor than connect a 100 ohm resistor with Blue led and 220 ohm resistor with Red led.



Image: Connections

After completing the connections , Open Arduino IDE and upload the code. The Code is shown below.                                    The two LED’s are connected on PIN 5 & 6.


Board Selection :

Now open tools menu and select the Arduino uno/Genuino from the board option.


After selecting the board option we have to tell to the Arduino IDE on which port Arduino UNO is connected. So click on tools menu and select the port option and choose the port on which Arduino is connected.
















After Selecting the right board and port upload the program with the help of Upload button .If you followed every step mentioned above your Led should have started blinking.
