Step 2: Finding the pins to connect to
Got your datasheet ready? Great! We'll need it now. Go to the "Pin configuration" page.
Write down where the following pins on your MCU are:
- RESET
- SCK
- MOSI
- MISO
This is the same for all equally-pinned AVR MCU's. That means if you have soldered an 28-pin IC socket you can safely replace the MCU with any other 28-pin variant (well, check the datasheet, I'm not a guru yet!). I tried this with a Atmega8 and Atmega328, which are both DIP-28. This should also be the same for Atmega168 and several others, so if you have any of those... simply use the image below.
We're going to connect our ICSP header to these pins, see the next step!
