With the comparator output driving an LED, the next step will be to sense the intensity of the LED. This lab will build a light detector cir...

The schematic diagram for the circuit is given in the picture above. Like its name suggests, a comparator compares two given voltages. The p...

The circuit on this page is for a visible and infrared light detector circuitboard that has 8 detectors. LM339 voltage comparators are the a...

The circuit"s threshold is set by resistor R2. When the intensity of the light falling on the LDR is lowered, resistance of ...

This circuit give low level output, when exist enough lighting, that is a detector of light. It can give, say ,command turn on somebodies li...
