Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

Blinking an LED with three resistors and a capacitor. Ok, ok… one of the resistors is a light-dependent resistor, but still. In reality, this is a classic relaxation oscillator.

In this experiment we are going to use a element called photoresistor. This sensor allows us to interact with the external environment, through intensity of light. The photoresistor is based on light ...

This water sculpture can stop drops of water in mid-air. This is accomplished by flashing LEDs to illuminate the droplets at just the right time. But it’s not limited to blinky lights alone. … ...

There's something magical about the Periodic table of elements, and even more so if the meaning is illuminated with LED lighting! Thanks to the Arduino team for highlighting this one - a group of ...

Alternatively, the LEDs could be configured as track lamps with up to fourteen 4W LEDs – each lamp would deliver the light output that is equivalent to a 40W halogen bulb with equal or better light ...
