Adafruit has this week announced the arrival of the new Arduino RGB Matrix Shield which is now available to purchase priced at $5.95. Any of your projects that use a Arduino-compatible board, equipped ...

There are so many nice hacks in [Joekutz]’s retro LED display project that it’s hard to know where to start. There’s his DIY LED display controlled by an Arduino UNO. To have some text or picture for ...

A word clock – a clock that tells time with words, not dials or numbers – is one of those builds that’s on every Arduino neophyte’s ‘To Build’ list. It’s a bit more complex than blinking a LED, but an ...

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 ...

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 ...

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 8x13 blue LED matrix is also an example of using PWM to implement gray-level images. The LEDs are connected in a row/column layout in the form of a tree – the first row has one LED pair, the ...

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 ...

The Ulanzi TC001 is a small Wi-Fi clock built around a 32 x 8 RGB LED matrix. It’s compact, bright and just retro enough to be charming without looking like something dragged out of an arcade cabinet.
