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 ...

Arduino Nano 3.0 (ATmega328). Real Time Clock DS3231RTC. 32x8 LED Dot Matrix Display Module (with MAX7219 chip). LDR sensor.

This project shows a LED matrix panel with 64x64 full RGB pixels driven by a ATMega-2560 Arduino. I added a Real Time Clock TinyRTC_DS1307 to show the time. This display was created to help teachers ...

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 ...

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 ...

Just when we think we’ve seen all possible combinations of 3D printing, microcontrollers, and pretty blinkenlights coming together to form DIY clocks, [Mukesh_Sankhla] goes and builds this geometric ...
