Is there an ADC GPIO I can use on the ESP32-CAM to read and LDR? - Project Guidance - Arduino Forum

My Arduino project essentially consists of an ESP32-CAM sending a photo to my Telegram group every 15min, then goes to sleep. When it wakes up, it evaluates the "brightess level" by reading the voltage from an LDR, if the brightness level is too low (night time), it goes back to sleep; otherwise it connects to the internet, takes a photo and sends it to me. I am aware the ADC pins of the ESP32 are distributed between ADC1 and ADC2 and that ADC2 should not be used when Wifi driver is in use. I a
