* taking the photoresistor from your 147A kit, it has a resistance of ~140k - ~800 (depending on your lighting conditions)
* Q: With the same R2 resistor (10k) from above, replacing R1 with the photoresistor, what range of voltages (and corresponding data values) would you expect to see at your A_IN pin?
