AnalogPin is an Arduino class that adds noise filtering and smoothing to analogRead(). Furthermore it can speed up the analogRead() function by tuning the pre-scaler. This latter is AVR only.

As explained by Arduino to Go, each color band on the resistor corresponds to a number but this can differ depending on the band's placement.It's not complicated, but the sheer number of colors ...

An Arduino can measure time, a coil and a resistor will create a delay proportional to the circuit values, and metal around the coil will change the coil’s inductance.

Line 8 is the starting of the cycle that is going to perform while Arduino is powered on. Line 10 is used for reading analog values from photoresistor and storing the values to a variable called “int ...

In the Arduino community there are two solutions (hacks) to this: add a couple of ms delay between measurements on different pins; perform two analogRead() on the same pin, dump the first and keep the ...
