The photoresistor registers about 140k ohms in inside natural light, held under the bike seat. In the bathroom with the door mostly shut, simulating nighttime, it registers 22M. Tentative initial ON value: 20Mohm. | The photoresistor registers about 140k ohms in inside natural light, held under the bike seat.
