Many microcontrollers include timer circuits, but only a few include a battery-backed real-time clock (RTC). Yet many applications require an RTC, which you can easily add by using a 1-Wire network.
The DS3231M is a low-cost, extremely accurate, I2C real-time clock (RTC). The device incorporates a battery input and maintains accurate timekeeping when main power to the device is interrupted. The ...
A lot of microcontroller projects out there need some sense of wall-clock time. Whether you’re making (yet another) crazy clock, logging data, or just counting down the time left for your tea to steep ...
