Hey guys this video shows how to make a Day/Night sensor which will turn on during the night and off in the day.
This is not my creation but I thought it was really cool and I couldn't trace it back to a specific person since its been around for a long time.
your welcome and thank you for the sub =]. And yea when I first saw this creation I was just in awe lol I use it for so much in my creations now I have fountains that come on during the day and go off at night, glowstone that goes away during the day and out at night. Also want to make a town that closes up at night and opens during the day =]
thats a nice day/night sensor. its funny i built one with 12 each of day and night mode sensors and its actually faster when switching to day mode. one thing you can do is put some torches or other light sources and then have it so that pistons will then block them off during its day to night mode.
