Getting Started with Arduino – LED Blinking

Arduino LED Blinking (1)

Arduino Uno is the best development board for beginners in the field of embedded systems. We can program Arduino board with less technical knowledge and programming skills. This tutorial is intended to beginners in the field of Arduino. Hope you already have an Arduino board. Then you have to download Arduino Software and Driver. You can download it from Arduino Website.

Installing Arduino Driver

Now connect the Arduino to your computer using a USB cable. As usual Windows may start driver installing procedure but it will fail after some time. We need to install driver manually which comes along with Arduino Software.

You can find Arduino under the Ports (COM & LPT). If it is not listed there, look under Other Devices >> Unknown Device.

Double Click on the Unknown Device, you can see details.

elect “Browse My Computer for driver software”
Hope you successfully installed driver.

Now we can start Arduino programming. All of us start learn a new programming from Hello World. In microcontroller fields the Hello World example is usually blinking an led. In Arduino Uno, there are 4 on-board LEDs. One for indicating power, two (RX and TX) for indicating serial communication between Computer and Arduino. The remaining one is connected to PIN : 13. Thus when the digital pin 13 is HIGH, LED turns ON and when it is LOW, LED will be OFF.

Firstly we can start by blinking this on board LED. Arduino IDE comes with a lot of examples, which makes our task simpler.

  • Open the Arduino IDE
