INPUT_PULLUP mode #10

Open joihn opened 8 years ago

joihn commented 8 years ago

I am working with arduino IDE.

Here is my problem : if I set one of the pin (pin 0) in INPUT_PULLUP mode, then the pin isn't actived by connecting it to 3.3v, but by connecting it to ground..... This is strange !

Any idea why ?
