- **Light Dependent Resistor (LDR) Modules:** These are electronic components that detect light levels. - **Output Text:** - "PWR-LED" - "DO-LED+" - "DO GND VCC" - "3362" (likely part of a component marking) - Some other numbers and symbols on components (e.g., "4704") - **Usage:** These modules are used to sense ambient light. They can be incorporated into projects that need to react to light conditions, such as automatic lighting systems, light-activated switches, or light intensity measurement. - **Additional Information:** The modules appear to be designed for microcontroller projects (like Arduino or Raspberry Pi) as they have pins for power (VCC, GND) and digital output (DO). The potentiometer on each board likely allows for adjusting the light detection threshold.
