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 ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

The code in loop () is executed repeatedly as long as the power to the Arduino is supplied. Even if you power off the Arduino and power it back on, the sketch still resides until you overwrite it with ...

To do this in Arduino/C code, a new intermediate position for the servo is specified for each main loop until it reaches the final position.
