void setup() { pinMode(3, INPUT_PULLUP); }This can be useful when you don’t want a pin to be floating, e.g. when you connect a button to a pin.Note that the analog pins can also be used as digital pins, using the aliases A0, A1, etc. The exception is the Arduino Nano’...
When the pin is HIGH value, the LED is on, when the pin is LOW, it's off. The Nano has 8 analog inputs, each of which provide 10 bits of resolution (i.e. 1024 different values). By default they measure from ground to 5 volts, though is it possible to change the upper end ...

The SI unit of capacitance is Farad, or F. This is a very large unit, and most often, you'll see prefixes like pico (p), nano (n) or micro (µ). On some smaller capacitors, the capacitance is written using a three-digit number. The first two digits are the first two digits ...
