P10 Pin → Arduino Pin nOE → D9 (Output Enable, active low) A → D6 (Row select A) B → D7 (Row select B) CLK → D13 (SPI Clock) SCLK → D8 (Shift clock) R_DATA → D11 (SPI MOSI) ...

We’re big fans of the impractical around here at Hackaday. Sure there’s a certain appeal to coming up with the most efficient method to accomplish your goal, the method that does exactly what it needs ...

Esoteric clocks are something of a staple among hardware hacker projects. If it can be made to tell the time correctly, even if only twice a day, the chances are someone’s made a clock from it. And if ...

This project shows a LED matrix panel with 64x64 full RGB pixels driven by a ATMega-2560 Arduino. I added a Real Time Clock RTC_DS3231 to show the time. This display was created to help teachers in my ...

Binary Clock is a clock that displays the current time in binary or decimal using a LED display. It really does not serve much of a practical purpose, unless your goal is to display the time in a ...

It’s amazing what you can make with a blonk of acoustic guitar wood, a string of LED lights, and some basic coding knowledge. Surely someone with a healthy imagination could figure out various ways to ...
