Connect a 16MHz external crystal between pin 9 and pin 10 of the Atmega328. The Atmega328 is the main component on our breadboard. The 5V output will be shown by the LED used. A 10uF capacitor is used at input and output of LM7805 to bypass any AC component to ground. This is to keep the voltage regulated, however, if you have a 5V supply, leave this step. We are using LM7805 to get 5V output as the Atmega328 IC runs of 5V power supply. Components Required:ĮlectronicsLovers official Online Store – Pin Diagram of Atmega328 Circuit and Components Description: First, we will have to burn the Arduino Bootloader and then program it using FTDI or Arduino board. In this project, we will be replacing the Arduino board with Atmega328 IC and other components. Instead, we can use Standalone Atmega328 IC which can be programmed with Arduino IDE without using the Arduino board. Arduino board is popular for use in projects but is not suitable for industrial use. 6 How to Program Arduino Bootloader uploaded Atmega 328 IC:Ītmega328 IC is the brain of the Arduino board.5 Making your Own Arduino Running on Breadboard:.
