According to this datasheet, the ATTiny85 has 6 I/O pins if we include the reset pin. I used five of them to charlieplex 18 LEDs and I need another one to use as analog input.
Would it be possible to use the reset pin either as an analog input or as a digital output? If so, how? I tried controlling LED's with the reset pin, however it kept resetting my board really fast, so that's not how you do it.
Which is simpler, reset pin as analog input or as digital output and how would I manage that?
