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 ...

Here is a simple, yet useful circuit of an Arduino 4-digit 7-segment LED display unit. The module used here is a self-contained, compact common-cathode module containing four 7-segment LED numeric ...

(D6 of Arduino connected to Din of WS2812B) It is highly recommended to connect a 100nF capacitor across the ‚5v and Gnd‛ connection, and a 100-470 Ohm resistor in series with the ‚Din‛ line of the ...

Driving an LED and making it flash is probably the first project that most people will have attempted when learning about microprocessor control of hardware. The Arduino and similar boards have an … ...

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 ...
