Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. Anyone interested in creating interactive objects can “play” with Arduino! Described ...

Do this before you sew anything onto your sweater just to make sure the LED string will correctly fit the pattern you drew. Start with the end of the string so the Arduino ends up at the bottom of ...

Auf einer LED-Matrix lassen sich mit einem Arduino alle möglichen Texte und Daten anzeigen, etwa die aktuelle Temperatur. Wir erklären, wie das funktioniert.

The Arduino then controls the state of the LED using the active high enable line from the column multiplexer chip. [Alex] wanted more than just a static image to show off on his new display, so he ...

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...

The on-board 12 x 8 (96pixel) matrix of red LEDs (photo right) is Charlieplexed for pixel-level addressing. Arduino_LED_Matrix API is available for programming and control, and “we have developed a ...

Inside, an Arduino Nano is hooked up to a series of WS2812b LEDs. The LEDs are flashed in time with the heartbeat of the person holding the heart, thanks to a MAX30102 heartbeat sensor.
