FAQs on Arduino Tut. #5 - Bootloader Burning with AVR ISP MKII

1. What is a bootloader and why is it important in Arduino programming?
Ans. A bootloader is a small piece of software that allows the Arduino board to be programmed through the USB or serial port. It is important because it eliminates the need for an external programmer, making it easier to upload new sketches to the Arduino.
2. How do I burn the bootloader using AVR ISP MKII?
Ans. To burn the bootloader using AVR ISP MKII, follow these steps: 1. Connect the AVR ISP MKII programmer to the Arduino board. 2. Open the Arduino IDE and select the appropriate board and port. 3. Go to Tools > Burn Bootloader and select the AVR ISP MKII as the programmer. 4. Click on the Burn Bootloader button and wait for the process to complete.
3. Can I use a different programmer to burn the bootloader?
Ans. Yes, you can use a different programmer to burn the bootloader. The process may vary depending on the programmer you are using. However, the general steps involve connecting the programmer to the Arduino board, selecting the appropriate programmer in the Arduino IDE, and clicking on the Burn Bootloader button.
4. What are the advantages of using a bootloader compared to an external programmer?
Ans. Some advantages of using a bootloader are: - No need for an external programmer, which saves cost and space. - Easy and convenient uploading of sketches through the USB or serial port. - Allows for in-system programming, meaning you can upload new sketches without physically removing the microcontroller from the board.
5. Can I burn the bootloader using a different Arduino board as the programmer?
Ans. Yes, you can use a different Arduino board as the programmer to burn the bootloader. This is called using Arduino as ISP. The process involves uploading the ArduinoISP sketch to the programmer board, connecting it to the target board, and selecting Arduino as ISP in the Arduino IDE before burning the bootloader.
