Exploring the Relationship Between Photoresistor Current and Light Intensity Using Phyphox and ESP32 Bluetooth
Recently, we conducted an experiment to explore the relationship between the current of a photoresistor and light intensity. The photoresistor and a voltage divider resistor were connected in series, powered by the 5V output of the ESP32. We used pin IO33 to collect the voltage across the voltage divider resistor and calculated the current through … Read more
