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 ...

A custom clock built from scratch using an Arduino Nano, a Max7219 dot matrix display, and an RTC DS3231 real-time clock module, with a custom-designed PCB. This project is based on the Arduino Matrix ...

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 ...

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 ...

Electronics enthusiasts or those looking to learn more about electronics may be interested in a DIY word clock which has been created using a little Arduino programming, Arduino development board and ...

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 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 ...
