Arduino UNO ISP Shield Updated PCB

What is an Arduino ISP?

An Arduino ISP (In-System Programmer) is a feature that allows the Arduino UNO to program other AVR microcontrollers directly on the target board. This eliminates the need for an external programmer and simplifies the programming process. The Arduino UNO can be configured as an ISP using the built-in SPI (Serial Peripheral Interface) pins and the appropriate firmware.

How does the Arduino ISP work?

The Arduino ISP works by establishing a communication link between the Arduino UNO and the target AVR microcontroller using the SPI protocol. The SPI protocol is a synchronous serial communication interface that operates in a master-slave configuration. The Arduino UNO acts as the master, while the target AVR microcontroller acts as the slave.

The SPI pins on the Arduino UNO are as follows:

To program the target AVR microcontroller, the Arduino UNO sends programming commands and data over the SPI interface. The target AVR microcontroller receives these commands and writes the program into its flash memory.

Benefits of the Arduino ISP

Using the Arduino UNO as an ISP offers several benefits:

1. Cost-effective: The Arduino UNO is an affordable microcontroller board, making it an economical choice for programming AVR microcontrollers.
