2 questions for you.

1- which resistors did admin order?
2- which one did he use for the led?

340ohm
1.62K

don't know which one he used for the LED

I think (70% sure) that I used the blue one. I can't check because it's covered in heatshrink. Wait for someone good to answer.

340 ohm for the led sounds right

i use a 10K ohm resistor on my photocells though
