Sundial alarm
Jan. 14th, 2014 10:15 pmSF0 has a task, "Make a sundial. Use it!"
I have yet to make a sundial, but I have been reading about them, and how to construct them. (Make a sundial.)
I wanted to involve some electronics, so I have been playing with an Arduino and an LDR (light dependent resistor). I used the instructions here Arduino UNO: PhotoCell - sensing light.
I want to place the light dependent resistor so that when the shadow hits it, then it will tell me the time somehow. Perhaps it will tweet the time or just make a noise like an alarm clock.
(Yes, I know I could just look at my watch to see the time and this is all quite pointless.)
