When you’re building a clock, or a datalogger, or anything that relies on a stable sense of passing time for more than a few minutes, you’ll want a Real Time Clock. So called due to their ...

The Real Time Clock (RTC) SGC22300 uses the leading oscillator solution SGC21510. This specially designed RTC core uses advanced analog design techniques to guarantee ultra low power consumption ...

The build relies on that old stalwart, the Arduino Uno, to run the show. It’s hooked up to a DS3231 real-time clock module so it can keep accurate time for long periods, as is befitting a clock.

Real-time clock (RTC) modules are increasingly being designed with ultra-low power modes to extend battery life. But that’s ...

This proposed Arduino-based automatic bell device is an electronic system that rings bells at predefined times without manual ...

2 is a great package. An interesting feature on the datasheet is a built-in RTC (Real Time Clock) which receives power via a CR1220 batter and a "SuperCAP" (Super Capacitor) which can quickly ...
