Upload this code to you Arduino UNO in order to turn your Arduino UNO board into an AVRISP Programmer.ДЄfter completing this step, make the necessary connections (if not made already). Now, go to File > Examples > ArduinoISP > ArduinoISP. So, before making the connections, connect the working Arduino UNO to the computer using USB cable and select the appropriate board and PORT in the Arduino IDE. In order to achieve that, you have to upload a special program onto your working Arduino UNO board called вЂњArduino ISPвЂќ. Procedure for Programming Bootloader on Atmega328ДЄs mentioned earlier, Arduino UNO is being used as an AVR programmer here. Pin diagram of the ATmega328 Microcontroller is shown in the following image, just in case. The circuit diagram for burning bootloader on ATmega328 Microcontroller using Arduino is shown below. In this project, I will be using the second method i.e. The second way is to use a working Arduino board as the programmer and burn the bootloader on the target ATmega328 Microcontroller. The first way is to use a Dedicated AVR Programmer Hardware. There are couple of ways to burn bootloader on ATmega328 IC. Once the ATmega328 Microcontroller is ready with bootloader, you can simply use it in your Arduino Board (as a replacement) or use it as the microcontroller if you are planning to make your own Arduino board.

But if you burn Bootloader on ATmega328, you can simply program the microcontroller over serial port (USB cable). What is the need for Burning Bootloader on ATmega328?ДЄs I mentioned earlier, if you want to upload programs onto a brand new ATmega328 Microcontroller IC, you have to use a special programmer (and also set the fuse bits). just by using an USB cable.Д«ootloaders resides in a special secured location of the Programmable Flash Memory of the Microcontroller and usually occupies less than 1KB of memory. Bootloaders take out this complexity and provides us with an easy way of programming the microcontroller i.e. Traditionally, microcontrollers like ATmega328 from Atmel are programmed with the help of dedicated programmers which involves some fancy connections. The job of Bootloader in Arduino is to accept the code from the computer and place it in the memory of the microcontroller. Bootloader in Arduino allows us to program Arduino over serial port i.e. hex format) that resides in the MicrocontrollerвЂ™s memory.

Simply speaking, Bootloader is small piece of code (executable code in.

WARNING: It is not recommended to tweak the Bootloader in Arduino if you are new to this kind of stuff.

There are other reasons for burning Bootloader on ATmega328 Microcontroller like if you have written your own Bootloader and want to test it out or you want understand the working of microcontroller in detail. In order to reuse that Arduino Board, you need a new ATmega328 IC with Bootloader loaded (I will talk about Bootloader in a minute). There is a high possibility that the ATmega328 Microcontroller on Arduino UNO might fail after certain time (or improper connection). If you are viewing this project, then you might probably have used Arduino board.
