Okay, I'm using 2 photocells in parallel with a smaller resistance in series in order to activate a relay.
But it's not working too well. So I'm troubleshooting lately.
But I have all the tasks complete now! I'm excited for regionals in 1.5 weeks.

Shouldn't need - or want - a resistor going to the relay....

Um... Well, the problem is that my photoresistor resistance is too high, even in high-light conditions.
So I'm putting them in parallel with a lower resistance, after experimenting with some variable resistors. But I figured out why it's not working: somehow little bits of iron got in the gap of my relay. So, we'll see how it works tomorrow
