Hi, I'm a beginner. I try to program an Attiny85 by Arduino Uno as ISP. When I turn the power of the Attiny85 off, by disconnecting the Vcc, it remains on as long as the input is high (the Vcc and the input have two different power source grounded together).
I wonder if it's because of the inernal pullup of the Attiny85. If so, how can I disable it? I defined the pin as an INPUT not as an INPUT_PULLUP.
Thanks!
