![]() These are useful for reading potentiometers or other analog devices using the analogRead() function. Nine pins feature analog to digital converters (ADCs) and can be used as analog inputs. (The A0-A3 pins can be referenced digitally using either their analog or digital pin number). These pins are referenced in the Arduino IDE via an integer value between 0 and 21. Every pin can be used as a digital input or output, for blinking LEDs or reading button presses. The Pro Micro's I/O pins - 18 in all - are multi-talented. GND, of course, is the common, ground voltage (0V reference) for the system. ![]() The Pro Micro will remain "off" until the reset line is pulled back to high. This pin is pulled high by a 10k&Ohm resistor on the board, and is active-low, so it must be connected to ground to initiate a reset.
