What is an Arduino ?

Getting
Started with
Arduino UNO

Arduino Uno

Although there are many types of boards from arduino . Here we are going to be using the Arduino UNO as it is the most commonly used one. The arudino UNO has :

The operating voltage is 5V
The recommended input voltage will range from 7v to 12V
Digital input/output pins are 14
Analog i/p pins are 6
DC Current for each input/output pin is 40 mA
Flash Memory is 32 KB
SRAM is 2 KB
EEPROM is 1 KB
CLK Speed is 16MHz

Another wonderful feature of the arduino is the option of using a add-on boards to the arduino which comes as a module and they are known as “Shields”

Let's get Started. We have a lot in store for you.

Getting Started

Before you can start working with Arduino, you need to make sure you have the IDE software installed on your computer. This program allows you to write, view and upload the code to your Arduino Uno board. You can download the IDE for free on Arduino’s website.

Once the IDE is installed, you will need to connect your Arduino to your computer. To do this, plug one end of the USB cable to the Arduino Uno and then the other end of the USB to your computer’s USB port.

Select The Board

Once the board is plugged in, you will need to open the IDE and click on Tools > Board > Arduino Uno to select the board.

Select Serial Port

Next, you have to tell the Arduino which port you are using on your computer. To select the port, go to Tools > Port and then select the port that says Arduino.

Project Code

To complete the projects in this tutorial for beginners, you will need to download the project code which is known as sketches from our website after the purchase of the kit. A sketch is simply a set of instructions that tells the board what functions it needs to perform. For some of these projects, we are using open-source code that was released by the good people at Sparkfun and Arduino. Use the link below to download the zip folder containing the code.

Once you buy the kit you will be able to download the codes/sketches. File which has been downloaded, you will need to unzip/extract the folder in order to use it.

Troubleshooting

Make sure your board and serial port is selected in the IDE. To do this, plug your board in and go to Tools > Board >Arduino to select your board. Next, go to Tools > Port >Com (Arduino) to select your serial port.
The long leg of the LED is the (+) positive and the short leg is the (-) negative. Make sure the correct leg of the LED is in the proper pin of the Arduino or breadboard as directed.
It can be easy to put a component or jumper into the wrong pin on the Arduino or the breadboard. Double check the correct pin is being use
