Step 3Setup II
Setup Cntd.
(1) set up the circuit on a breadboard according to the diagram (first image). You can test out the photoresistor by covering it with your hand (second image).
(2) make sure to have all of the power supplies for your circuit plugged into a surge protector (i.e. a power strip with a circuit breaker)
(3) calibration:
You'll have to change your screen brightness setting to one that works best. i.e. the brightness at which the photoresistors won't conduct electricity when the screen is black, but will conduct enough electricity when the screen is white to activate its transistor/relay. I found that with some photoresistors I had to put a piece of paper between them and the screen to help modify the brightness getting to it (see previous note).
