Tell us about yourself!
Maybe a bit too late but this can be achieved by using "mfrc522.PICC_IsHaltPresent" This will keep checking if the card is still present.
Automatic Arduino Powered Pet Feeder
Absolutely fabulous!! very nicely done.
Howdy Kapitein Haak,Good effort!! Now I need to make one as well, most likely I will use a radar module instead of IR, just because I already have it lying around. Still a couple of weeks to go, should be fine. ;p
LOL, love it!
love the instructable! I would personally go for welds. However a good whiskey (Bushmills 16y for instance ;p ) is there to enjoy so a couple of bars would have 'fake welds' like the ones of the welded bolt puzzle
Made my very first Jack 'o' lantern ever. Quite proud of the result. Thank you for the great design!!
Love them, will be making these for Halloween as well. You've got my vote!
Voted! Absolutely love the design, great instructable too! Thumbs up.
The Unix time has a small disadvantage, it also includes date. So I had to reset the date every day, not really full proof. Hence I ended up using a different library with alarm function:https://github.com/jarzebski/Arduino-DS3231It actually has 2 alarms, as I am using it for my aquarium it is perfect to trigger an on and off cycle.
Honestly I think that is what Instructables is all about, the fun of being able to build stuff yourself.Great instructable, if I wass still using a landline I would have followed your steps to create one myself.Keep up the good work rjkorn.
what an awesome aquarium stand and the instructions are very clear, it does show that this is not your first time working with wood, what a workmanship!I am currently looking for alternatives for my dresser as aquarium stand so this instructable is forwarded to the missus.
Howdy RubenS13, instead of /= you should be using == but for some reason it will still not work. I found that using the Unix time did do the trick, so something like:if (rtc.getUnixTime(rtc.getTime()) == 946745100)Hope this helps.
