Quick note: ATmega based Arduino boards (UNO, Nano, Mini, Mega) takes about 100us to read an analogue input, so the maximum reading rate is about 10,000 times second. Below you can see a “CIE1931 Fade ...

You can fade out and fade in the light of an LED automatically by using Arduino and a simple code that is described below. Even though the Arduino board cannot output variable voltage on its digital ...
