It's a resistor whose value will vary according to the intensity of the light it receives. ===== Cabling ===== To connect it to an **analog** input on an arduino, it must be connected to a high value resistor (typically 100K Ohms). The value read will range between 750 and 1023 for a strong light source received and less than 100 for obscurity. ---- {{composants:ldr_fritzing.jpg??300px}} composants/ldr.txt Last modified: 2025/01/19 10:37by mh
