Description

Circuit schematic like in Figure 1 above is Circuit Schematic Webcam Sight Illuminator uisng LM311 IC and AMC7135. Electroschematics site describe that a standard 5-mm photoresistor (LDR) detects the ambient light level, and its resistance drops when sufficiently illuminated. The resulting voltage level on one input of the single comparator LM311N (IC1) cuts off the reed relay (RL1) that is connected to the comparator’s output to keep the 1-W white-light LED (LED1) in the off state. When the LDR is not sufficiently illuminated, the output state of IC1 is reversed, thereby energizing the relay so that the LED connected to it is lit. The switching level can be adjusted with the 10-K multi-turn potentiometer (P1). The component values are not especially critical; however, the coil of the relay must have a very low operating current (no more than a few mA).
