WebFollowing table mentions difference between photoresistor and phototransistor . No, Photoresistor is sensitive to incident light from anywhere in front of it. Yes, … WebOct 27, 2024 · The negative input connects between two 10K resistors (between 3.3v and GND). From the positive input a 56K resistor connects to 3.3v and the photocell connects to GND. I put in a female header for the resistor so it can be changed for different values as necessary. I started with 4K7 but it didn’t switch to bright at a low enough light level.
