A clock based on 4 8x8 LED matrix modules with MAX7219, is controlled by an Arduino Pro Mini 3.3v, and includes a DS18B20 digital temperature sensor.

8×8 LED Matrix modules are now widely available, and fortunately they are easy to use with our favorite Arduino microcontroller. 8×8 LED Matrix module have many applications in real life, such as ...

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 ...

Listens to a mic attached to an Adafruit Flora (a small Arduino) and creates mouth movements on an 8x8 grid of Neopixels. Optional pop detection for a smile :) ...

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 ...
