Mike Szczys of Hack a Day wound up wiring 70 LEDs into a hollowed-out pumpkin, giving his gourd a programmable 5-by-14 LED matrix display.

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 ...
