Automatic light switch with timer and Arduino
I need to set up a test environment with End of Day lighting (EOD). I am a rose breeder and I read some interesting articles on the use of far-red light (740nm) followed by red light (660nm) for a short while at EOD. The goal is to lengthen the stems of the roses by giving them EOD light in a sequence.
What I need to achieve is that by dusk (EOD) the far-red goes on for 10 minutes and then off, followed by the red light for 10 minutes and then off as well utill the next evening.
I have the following hardware:
Arduino's (Uno and Mega)
LED's (red and far-red)
two relays to power the LED's transformer(s)
However: I am not a programmer. Can somebody help me with the code needed for this trial? As far as I can see it should be reasonably straightforward.
