Thanks for asking :) You are welcome! Your first question refers that there is no pin 0 on Attiny85. There is, however: Look at this page: https://learn.sparkfun.com/tutorials/tiny-avr-programmer-hookup-guide/attiny85-use-hints; Take special attention to Arduino IDE:1.6.4; when you run the Hello World Basic blink the idea is to blink the led attached on the hardware pin 5; It’s inside aTtiny85 Lib. The Capacitor C1 10uF is essential too; it avoids Arduino resetting. Hope that helps:)
