The dot matrix clock was built without the use of a regular Arduino board but uses the ATmega168 with Arduino bootloader and assembled on a breadboard. An RTC clock compensated by temperature is used ...

If you searching for an LED matrix for your next project or to add to an existing application you may be interested to know that the Maker LED Display is now available to purchase from the Crowd ...

When we last heard from [lixielabs] he was building Nixie tube replacements out of etched acrylic and LEDs. Well he’s moved forward a few decades to bring us the Pixie, a chainable, addressable ...

The circuit is driven by a MAX7219 IC that is being controlled through an Arduino microcontroller board, to create an 8X8 LED matrix. The connection of the LED matrix and the IC was done on a ...

Few things excite a Hackaday staff member more than a glowing LED, so it should be no surprise that combining them together into a matrix really gets us going. Make that matrix tiny, addressable, and ...

Arduino enthusiasts interested in creating a changeable RGB LED matrix might be interested in the new Pixie Chroma displays created specifically for the Arduino platform by the engineers and develop ...

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 ...
