To do this, you can go to the Tools tab and select burn bootloader. For example, the middle LED indicated if there is an error in programming. This code also supports three LEDs which are used to check the operation of the process. In this example code, you can see many comments which will guide you through setting out different parameters. The next step to use an example code present in the Arduino examples section as ArduinoISP. To do this, go to the tools tab in Arduino IDE and set the programmer as Arduino as ISP.
The first step is to set the programmer Arduino as ISP.
Connect the two Arduino UNOs as shown in the figure. For example, if you want to program the bootloader of an Arduino UNO with another Arduino UNO. You can check the pin configuration of your Arduino board for that. First, you need to check where the ICSP pins are on your Arduino board. If this is the case, or you want to program the bootloader or program another microcontroller, you can use another Arduino board to do this. Sometimes this bootloader gets crashed, and the Arduino cannot communicate with the PC. When you connect the Arduino with your PC, the bootloader waits for a sketch to be uploaded to the microcontroller, and if no sketch is provided, the bootloader will run the already present sketch inside the microcontroller flash memory. The bootloader is preprogrammed and is inside the microcontroller’s flash memory. There is a bootloader in every Arduino provided by the Arduino team itself, which communicates with the PC and gives instructions to the microcontroller to perform some task like BIOS present in a motherboard.
