We’re surprised we haven’t seen this kind of clock before, or maybe we have, but forgot about it in the dark filing cabinets of our minds. The above picture of [danjhamer’s] Matrix Clock doesn’t quite ...

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 ...

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 ...

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 ...
