Easy application programming using open source IDE.It has everything needed to support the microcontroller, you need to simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started. Arduino Uno has 14 digital input or output pins(where 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. For instance in applications involving controlling some actuators like motors, generators, based on the input from sensors.The Arduino Uno R3 Compatible Board is a microcontroller board which is based on the ATmega328. You can use it for many types of applications. So this is some basic idea regarding an Arduino. It comes with an easy provision of connecting with the CPU of the computer using serial communication over USB as it contains built in power and reset circuitry.We can develop an Arduino based project which can be completely stand alone or projects which involve direct communication with the software loaded in the computer.It also comes with open source software feature which enables experienced software developers to use the Arduino code to merge with the existing programming language libraries and can be extended and modified.The Arduino software is compatible with all types of operating systems like Windows, Linux, and Macintosh etc.It comes with an open source hardware feature which enables users to develop their own kit using already available one as a reference source.Upload the program on the Microcontroller of the readymade Adruino and then pry it off and place back on the user kit.ħ Reasons why Arduino is being preferred these days.Mount the row of 6 male headers, which can be used as an alternative to upload programs.Mount the female headers onto the board and connect them to the respective pins on the chip. Connect the led to the appropriate pin.Connect the crystal oscillators to pins 9 and 10.Connect the reset pin of the IC socket to a 10K resistor.Add proper power connections to the microcontroller pins.Add the 5v and 3.3v regulator circuits using the combinations of regulators and capacitors.The IC socket and the power jack are mounted on the board.All we need are the following components- A breadboard, a led, a power jack, a IC socket, a microcontroller, few resistors, 2 regulators, 2 capacitors. We can also design our own Arduino by following the schematic given by the Arduino vendor and also available at the websites. serial.begin(baud rate): Sets the beginning of serial communication by setting the bit rate.analogWrite(pin, value): Writes the value to that pin.analogRead(pin): Reads and returns the value.pinMode(pin, mode): Sets the pin to input or output mode.digitalWrite(pin, value): Writes the digital value to the given pin.digitalRead(pin): Reads the digital value at the given pin.Thus the code is uploaded by the bootloader onto the microcontroller. Click on the upload button or chose upload from the tools menu.Chose the proper board from the tools menu and the serial port numbers.The sketch should be stored in the sketchbook directory.Any operations like verifying, opening a sketch, saving a sketch can be done using the buttons on the toolbar or using the tool menu.
