Reads the specified input port pin.翻译
WebPORT is the OUTPUT buffer, PIN is the INPUT buffer. When you want to set the pin to a "high" or "low" voltage, write to the PORT register. When you want to know what voltage is currently presented to a pin, read the PIN register. The bits of these registers represent the corresponding pins of the general-purpose input/output port. Web1 day ago · Notes and Warnings. If the pin isn’t connected to anything, digitalRead () can return either HIGH or LOW (and this can change randomly). The analog input pins can be used as digital pins, referred to as A0, A1, etc. The exception is the Arduino Nano, Pro Mini, and Mini’s A6 and A7 pins, which can only be used as analog inputs.
