#192 Wakey, wakey! Let the DS3231 RTC wake up your Arduino - easy!
Use a cheap RTC to wake up your Arduino from Deep Sleep JLCPCB Only $2 for PCB Prototype any colour https://jlcpcb.com/ More information (including all links, sketches & PDFs in my GitHub): https://github.com/RalphBacon/192-DS3... INFORMATION The DS2131 library I'm using in this demo (I do wish each developer used a unique name!) https://github.com/rodan/ds3231 Alternative DS3231 library by Northern Widget, has some nice features https://github.com/NorthernWidget/DS3231 DS3231 Datasheet.
