Introduction to Arduino Uno R3 Atmega328
Arduino is a microcontroller platform that
is based on an open-source electronics prototype.
It is easy to use the Arduino Integrated Development Environment (IDE)
and consists of both a physical programmable
circuit board and a piece of software. The Arduino is one of the more popular boards and is best for beginners with Arduino uno pin diagrams.
Major Components of Arduino Uno R3
USB Connector
The USB connector is used to load a program from the Arduino IDE.
Power Port
The Arduino board can be powered through an AC-to-DC charger or a battery.
Atmega328P
The Atmega328P microcontroller has the following components:
- Flash memory of 32KB
- RAM of 2KB
- CPU that fetches instructions from flash memory and controls everything
- EEPROM of 1KB (Electrically Erasable Programmable Read-Only Memory)
- Pre-programmed IC with a bootloader
Digital Pins
0 to 13 pins are digital and used for digital data.
Reset Switch
The reset switch is used to reset the Arduino.
Crystal oscillator
The crystal oscillator has a quartz crystal that ticks 16 million times a second.
USB Interface
The USB interface chip converts the signals into a format that the ArduinoR3 board can understand.
TX RX Indicator
TX is used for transmitting data and RX is used to receive data.
