Arduino Real Time Alarm Clock DS3231 with TM1638. Arduino Clock with Battery backup (real time clock), Time, Date, Alarm, Temperature, TM1638 seven segment module output and input, Display Sleep mode.

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 ...

This project demonstrates how to implement a real-time clock using the DS3231 RTC (Real-Time Clock) module and an Arduino. The DS3231 module is a low-cost, highly accurate I2C RTC with an integrated ...

When we last heard from [lixielabs] he was building Nixie tube replacements out of etched acrylic and LEDs. Well he’s moved forward a few decades to bring us the Pixie, a chainable, addressable ...

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 ...
