Works fine for a while, then gets bad date somehow:
(first number is year ie 2012,2012,2065)
Any idea why this might happen?
I am not setting the date, only reading it. But when I see that it has gone bad, I do set the date, and it is fine for a while again.
Using arduino mega256, RTC_DS3234.h
Working fine on mega2560:
RTClib.cpp needed <arduino.h> replaced with <Arduino.h>
50 (MISO), 51 (MOSI), 52 (CLK), 53 (SS), GND & SQK grounded, VCC to +5
const int len = 32;
static char buf[len];
DateTime now = RTC.now();

I am running a fan with one at 230V 1.7A (>10A for very few milliseconds during startup). It doesn’t get noticeably warm when used 2-3 times per hour for 2 minutes on each time. During the summer it could be on for 8-10 straight hours.
Is that an acceptable use for this thing, or should I use a relay?
No public wish lists :(
