The circuit of light detector is very simple and easy to build with very few components. As you can see in the LDR circuit diagram, it can be a distinguished as two smaller circuits; a) Voltage ...

Absence of light is what causes darkness, and we can automatically detect darkness or intensity of light using a Light Dependent Resistor (LDR). The circuit can be integrated with other electronics ...

Designed to protect data lines that may experience destructive electrostatic discharge (ESD), Littlefuse has introduced the miniature four-channel bidirectional SP1015 Series TVS diode array (SPA ...
