To solve this problem, we can configure atmel atmega 328. Opensource electronic prototyping platform enabling users to create interactive electronic objects. It has more or less the same functionality of the arduino duemilanove, but in a different package.
In this tutorial, we will see how replace arduino board with atmega328 ic and with few other components. Our goal for this tutorial will be to understand how the arduino bootloader works and how an atmeg328p microcontroller can be flashed with it. Browse other questions tagged atmega328 or ask your own question. Drivers must be installed in order to be able to program an arduino from the arduino ide. First we need to tell our arduino uno in my case an arduino uno r1, to know that whatever we are sending is not for it, but for our other micro. I can only upload to the atmega328 by clicking upload using programmer under the sketch tab. All the arduino 00xx versions are also available for download. This basically turns the ic off and back on again so the bootloader can start running again. This is because after modify the configuration, atmega328 is recognized by arduino ide but atmega328p is not. Programming atmega328 with arduino ide using 8mhz crystal. If nothing happens, download github desktop and try again.
