![]() ![]() ![]() This is a type of nonvolatile memory, and it keeps the data even after device restart and reset.Ītmega328P is pre-programmed with bootloader. Electrically Erasable Programmable Read Only Memory (EEPROM) of 1KB.It fetches the program instructions from flash memory and runs them with the help of RAM. CPU : It controls everything that goes on within the device.The program loaded from Arduino IDE is stored here. Atmega328P has the following components in it: The microcontroller used on the UNO board is Atmega328P by Atmel ( a major microcontroller manufacturer). Think of it as the brains of your Arduino. It is the most prominent black rectangular chip with 28 pins. Microcontroller : Atmega328P microcontroller If the board is supplied with a higher voltage, there is a voltage regulator (it sits between the power port and USB connector) that protects the board from burning out. The Arduino UNO board operates at a voltage of 5 volts, but it can withstand a maximum voltage of 20 volts. The power source can be connected by plugging in a 2.1mm center-positive plug into the power jack of the board. The Arduino board can be powered through an AC-to-DC adapter or a battery. The board can also be powered through this port. This is a printer USB port used to load a program from the Arduino IDE onto the Arduino board. Now let’s take a closer look at each component. The major components of Arduino UNO board are as follows: In recent times, the UNO board has become synonymous with Arduino. This led to its increased adoption for electronic prototyping, creating a vast community of electronic geeks and hobbyists. However, the Arduino UNO board became more popular than other boards in the family because it has documentation that is much more detailed. There are other boards like Arduino Lilypad, Arduino Mini, Arduino Mega, and Arduino Nano. UNO is not the only board in the Arduino family. In this article, I will talk about what’s on the Arduino UNO board and what it can do. If you like experimenting with different electronic components but don’t have sufficient know-how, then Arduino is what you need to make a start…Īrduino is a microcontroller-based open source electronic prototyping board which can be programmed with an easy-to-use Arduino IDE. ![]()
