- It is basically a simple microcontroller board in which code(program or sketch) is written on it based on our requirement.
- There are many different boards available,out of which Arduino UNO board is mostly used as it is simple and easy to use for beginners.
- ARDUINO UNO BOARD
The Arduino Uno is a board based on the ATmega328 microcontroller operates at a voltage of 5V .It consists of
- 14 DIgital I/O pins(6 can be used as PWM output)
- 6 Analog input pins
- SRAM=2KB
- EEEPROM=1KB
- Flash memeory =32KB(Bootloader uses 0.5KB)
- 16 MHz clock speed ceramic resonator,
- Voltage regulator with 5V Output
- USB connection,
- Power jack,
- ICSP header, and
- Reset button.
- It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get it started.
- In order to burn(write a code on) the microcontroller,arduino software should be installed in computer.
- The Arduino programming Integrated Development Environment(IDE) software is used for coding which supports for C and C++ programming languages.
- This IDE converts the program into machine language or microcontroller understandable language.
- Once the program is loaded into the board through computer,arduino will perform the task specified in the program.
