Arduino
Leul
today we are going to see about ardunio since it is the basic component of almost all projects.
In the coming tutorials we will get you from introduction to building a project with arduino(this project,bluetooth controlled car,is actually built by our solver members)
So if you are specially an enginnering student it is worth to know about it since you are goinning to face about it in your coming lessons and assignments!
*ARDUINO*
Arduino consists of
both a physical programmable circuit board (often referred to as a microcontroller ) and a
piece of software
Arduino can
interact with buttons, LEDs, motors, speakers, GPS units, cameras, the internet, and even your
smart-phone or your TV! This flexibility combined with the fact that the Arduino software is
free, the hardware boards are pretty cheap, and both the software and hardware are easy to
learn has led to a large community of users who have contributed code and released
instructions for a huge variety of Arduino-based projects.
What's on the board?
There are many varieties of Arduino boards that can be used for
different purposes but most of them are similar
Every Arduino board needs a way to be connected to a power source. The Arduino UNO can
be powered from a USB cable coming from your computer or a wall power supply ( like this,see below )
that is terminated in a barrel jack. In the picture below the USB connection is labeled (1) and
the barrel jack is labeled (2) .
The USB connection is also how you will load code onto your Arduino board.we will post on
program with Arduino next time.
The pins on your Arduino are the places where you connect wires to construct a circuit
(probably in conjuction with a breadboard and some wire . They usually have black plastic
‘headers’ that allow you to just plug a wire right into the board. The Arduino has several
different kinds of pins, each of which is labeled on the board and used for different functions.
GND (3) : Short for ‘Ground’. There are several GND pins on the Arduino, any of which can
be used to ground your circuit.
5V (4) & 3.3V (5) : As you might guess, the 5V pin supplies 5 volts of power, and the 3.3V
pin supplies 3.3 volts of power. Most of the simple components used with the Arduino run
happily off of 5 or 3.3 volts.
Analog (6) : The area of pins under the ‘Analog In’ label (A0 through A5 on the UNO) are
Analog In pins. These pins can read the signal from an analog sensor (like a temperature
sensor ) and convert it into a digital value that we can read.
Digital (7) : Across from the analog pins are the digital pins (0 through 13 on the UNO).
These pins can be used for both digital input (like telling if a button is pushed) and digital
output (like powering an LED).
PWM (8) : You may have noticed the tilde (~) next to some of the digital pins (3, 5, 6, 9,
10, and 11 on the UNO). These pins act as normal digital pins, but can also be used for
something called Pulse-Width Modulation (PWM).these pins as being able to simulate analog output (like fading an LED in and
out).
AREF (9) : Stands for Analog Reference. Most of the time you can leave this pin alone. It is
sometimes used to set an external reference voltage (between 0 and 5 Volts) as the upper
limit for the analog input pins.
so solvers this is it for now next time we will see the other components on the board
stay tuned till then and yeah stay at home.
