Blinking LEDs are good. Moving, spinning things are good too. Put them both together and you get a Persistence of Vision (POV) display. Hackers have been building these displays for years. This week’s ...

In the world of smart homes, there are plenty of fantastic devices out there that can integrate well with Home Assistant and your other tools, and while dedicated sensors are great for their ...

Everyone loves LED matrices, and even if you can’t find what you like commercially, it’s pretty easy to make just what you want. Need it big? No problem; just order a big PCB and some WS2812s. Need ...

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 ...

Anyone who is wanted to create their very own LED matrix watch may be interested in a new project which is being entered into the The 2017 Hackaday Prize competition and has been created by user Mile.

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 ...
