==== photoresistor ====
* taking the photoresistor from your 147A kit, it has a resistance of ~160k - ~10k (depending on your lighting conditions)
* Q: With the same R2 resistor (10k resistor and setup ) from the schematic above, replacing the pot R1 with the photoresistor, what range of voltages (and corresponding data values) would you expect to see at your A_IN pin?* Q: Using methods you invented above, verify your data readings.
