My sketch queries a Real Time Clock, and depending upon the time, a digital pin switches to HIGH or LOW. I've tried both the Time and TimeAlarms libraries, but have ran into issues, plus have since found the RTClib to work well for me. I created a few different programmed events based on time, the …

Please post the whole sketch, or a cut-down sketch that compiles and runs and shows the problem.

The defines are because of the relay states are active high and it would confuse me when considering the desired end result. I will attach my whole sketch. Phase_1.ino (8.89 KB)

define# TURN_ON 0 define TURN_OFF 1 Spot the difference

Neither of which is correct, of course. if (now.hour() == 9 && now.minute() >= 0 && now.minute() < 10) // FeedPump1, ON 9am { ... } else // Turn off time for FeedPump1, OFF 9:10am { digitalWrite(Relay_B, TURN_OFF); } //******************* 2nd FEED TIME - RELAY B **************…

Let me put it like this ... if I said: If it is not 9 o'clock, slap yourself. If it is not 6 pm, slap yourself. Are you going to get a slap? If you aren't sure, try it out. You might even get two slaps. :wink:

UKHeliBob: Spot the difference Aren't they BOTH wrong? Shouldn't it be #define ? You might even get two slaps or just continuous slaps ? If it was my project I would test for the HOUR and then in a subsidiary test check the MINUTES just so I could understand what I was doing Something lik…

They way it is written, yes. Aren't they BOTH wrong? Indeed.

myggle: However, when I get to my second alarm, I fear my knowledge of the code is failing me and keeping me from asking the right question(s) of the RTC. Perhaps use the IPO principle and do a logical seperation of: Input Processing Output Do not try to mix input with just a small part of th…

Thanks for the feedback. I pasted the snippet about the test and mistyped the includes by mistake with hopes I would not have to explain why they were defined in the first place. Yet here I am again explaining them for other reasons. I was hoping someone would point out the flaws in my test(s) so I …
