Set pin to INPUT low

[Grzegorz]

Hi, how can I set pin mode to INPUT with low state?
When I use:
pinMode(p0, INPUT); p0 have 3,3V.
When i use:
digitalWrite(p0, LOW); p0 have 3,3V.
So, please share some code for example.

Thank’s.

Hi Grzegorz,
when you use INPUT It expects that the default state is LOW, to set an input pin to low you must add a pull-down resistor on your circuit.
