Arduino - MiniBootloader
Arduino - MiniBootloader:
How do I make the cable?
You need to connect 6 pins on the Arduino Mini to six pins on the ISP. The six pins are called MISO, MOSI, SCK, RESET, Power and Ground. Three of them correspond to digital I/O pins, numbered 11 - 13. The other three are the Reset, +5V and Ground pins you have probably already been using. (Note that you want to use the +5V pin, not the +9V pin. This is used to supply power to the ISP.)
These pins on the Arduino have to be connected to the corresponding pins on the 6-pin connector coming from the ISP, shown below.
