Connection used to program and Arduino or AVR chip with Raspberry Pi and avrdude

A working way (for me) to wire a Raspberry Pi to a logic level converter (http://www.arduiner.com/it/home/1973-logic-level-converter-33v-5v-ttl.html) and an AVR/arduino. The logic level converter is needed to preserve RPi GPIO pins fomr AVR's 5v, while using avrdude to program the AVR/Arduino. Tested and working with ATMega 328 and ATMega644. See external links to know how use it
