For that kind of cases we can still use Arduino programming to program Atmega 328PU IC microcontroller which is the same controller IC within the Arduino UNO board. Here we are using an Arduino UNO ...

Many MCUs, including AVR processors, can be programmed using an In-system Programmer (ISP) so they don’t have to be removed from the circuit board. By default, ... For example, in the Arduino UNO, the ...

The tutorial is fairly straightforward, and even demonstrates how the Arduino can be used as an ISP for the ATtiny, removing the need to purchase a standalone programmer.

Turning an Arduino of virtually any sort into a simple AVR 6-pin ISP programmer is old hat. But when Atmel came out with a series of really tiny AVR chips, the ATtiny10 and friends with only six pi… ...
