This will work even when not using an UNO. If you find this wiring more practical, have a define USE_OLD_STYLE_WIRING. That is why many tutorials instruct you to hook up the target to these pins. On some Arduino boards (see table above), pins MOSI, MISO and SCK are the same pins as digital pin 11, 12 and 13, respectively. Please note that the Rev.3 board has an ATMega 16U2 chip that manages the USB connection and also that chip can be reprogrammed via a dedicated connector labeled ICSP2, just above the ATMega 16U2 itself.

On the Arduino UNO in the following image, we have highlighted in red the connections on the female strips in yellow the ICSP connector that connects to the ATmega328P. Note that MISO, MOSI, and SCK are available in a consistent physical location on the ICSP header this connector is used also by shields that rely on the SPI interface allowing the design of shields that work on every board. The SPI interface - and therefore these pins - is the interface used to program the AVR microcontrollers.

The following table display on which pins the MOSI, MISO and SCK are broken out on the different Arduino boards: Arduino Board Three pins connect MISO, MOSI and SCK between the programming micro and the target micro, the fourth pin from the programming micro goes to the reset pin of the target. The programming process uses VCC, GND and four data pins.

The whole process of loading the bootloader code and burning properly the fuses to make an ATmega microcontroller an 'Arduino' is managed by the Arduino Software (IDE): it provides a specific menu item and allows you to use a variety of programming devices.ДЄmong the programmers, the 'Arduino as ISP' is the cheapest and most practical solution to burn a bootloader on another Arduino board with ATmega, 32U4 or ATtiny. The ISP programming procedure also includes the writing of fuses: a special set of bits that define how the microcontroller works under specific circumstances.

To program the bootloader and provide to the microcontroller the compatibility with the Arduino Software (IDE) you need to use an In-circuit Serial Programmer (ISP) that is the device that connects to a specific set of pins of the microcontroller to perform the programming of the whole flash memory of the microcontroller, bootloader included. This little (usually 512 bytes) piece of code is called the 'Bootloader' and it is in an area of the memory of the microcontroller - at the end of the address space - that can't be reprogrammed as a regular sketch and had been designed for such purpose.

If no connection is detected, the execution is passed to the code of your sketch.

The behaviour described above happens thanks to a special piece of code that is executed at every reset of the microcontroller and that looks for a sketch to be uploaded from the serial/USB port using a specific protocol and speed. It is enough to connect it to the computer USB port and press the 'Upload' icon to start a process that transfers your sketch into the Flash memory of the microcontroller. avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x1c avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x1c avrdude: stk500_getsync() attempt 3 of 10: not in sync: resp=0x1c avrdude: stk500_getsync() attempt 4 of 10: not in sync: resp=0x1c avrdude: stk500_getsync() attempt 5 of 10: not in sync: resp=0x1c avrdude: stk500_getsync() attempt 6 of 10: not in sync: resp=0x1c avrdude: stk500_getsync() attempt 7 of 10: not in sync: resp=0x1c avrdude: stk500_getsync() attempt 8 of 10: not in sync: resp=0x1c avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0x1c avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x1c An error occurred while uploading the sketch This report would have more information with 'Show verbose output during compilation' option enabled in File -> Preferences.What makes an Arduino what it is? Many things, but one of the most important ones is the way every Arduino board is easily programmed with the Arduino Software (IDE). Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Getting error Arduino: 1.8.5 (Windows 10), Board: 'Arduino Nano, ATmega328P' Sketch uses 926 bytes (3%) of program storage space.
