WebMay 5, 2024 · First thing, I would put a dropping resistor on the analog pins that the photoresistors are connected to. A 10k 1/4 watt resistor that goes from each pin to ground. This will help stabilize the signals you get from the sensors. This will change your threshold value but it will be much more stable. WebThis tutorial serves as a quick primer on resistive photocells', and demonstrates how to hook them up and use them. Beyond the light sensor, the following materials are recommended: Arduino Uno -- We'll be using the Arduino's analog-to-digital converter to read in the variable resistance of the photocell. Any Arduino-compatible development ...
