I'm using an Arduino Uno R3 as a programmer for my ATtiny85.
I know that you can enable the reset pin (IC pin 1) as an IO by burning a fuse bit, at the expense of losing the ability to program it again without 12 volts. However, can I use that pin as an analog input? I'm hoping to leave it unconnected, then use it as a seed for the random() function.
Also, how would I go about burning the fuse bit to enable the reset pin as IO with ArduinoISP?
