The gadget is built around two main circuit boards, the LED Matrix and the Host master board.In a previous project, I shared the making details of an 8x8 LED matrix. For this project, I expanded the ...

This project introduces a handheld game box equipped with temperature detection, catering to the need for portable entertainment and practical utility. Integrating classic gaming with real-time ...

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 ...

The driver uses the way the individual diodes of the matrix are wired and allows multiple diodes to be activated simultaneously within one cycle. This ultimately means that the refresh rate can drop ...

18 year old maker and developer Nikodem Bartnik from Poland, has created and awesome DIY Arduino-based dot-matrix printer, capable of creating art on paper 55 cm wide and as long as you need, thanks ...

Hackaday gets results! Reader [John] saw our recent Fail of the Week post about a “sand matrix printer” and decided to share his own version, a sand-dispensing dot matrix printer he built last year.

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 ...

After a youth spent playing with Amigas and getting into all sorts of trouble on the school computer network, I’ve always had a soft spot in my heart for hardware from the 80s and 90s. This extends ...
