The DS3231 RTC module is a real-time clock that uses less power and has highly accurate communication via an I2C interface. Also, the DS3231 real time clock has its temperature-compensated crystal ...
You want to determine precise times when the Arduino will run special code segments in a sketch, without using the timers and counters in the Arduino hardware. You have some skill and experience ...
This repo can be used to setup RTC clock (DS3231). The sketch includes a simple AT based serial communication protocol that can be used to set the time. The solution can be embedded into existing ...
