You’re asking what is LDR? It stands for Light Dependent Resistor or Photoresistor, which is a passive electronic component, basically a resistor which has a resistance that varies depending of the ...

Here, we are designing a simple light activated switch circuit using LDR. It can be used in security applications like when there is darkness on the LDR, it stops lighting. The main principle of this ...

If you ever built a line following robot, you’ll be nostalgic about [Jeremy’s] light-seeking robot. It is a very simple build since there is no CPU and, therefore, also no software. The trick, of ...

Photoresistors, also commonly referred to as light-dependent resistors (LDRs), are a class of variables resistors which change their resistance depending on how much light is hitting the resistor.

WARANGAL: Known for his low-cost innovations meant to address issues of people across villages, Mupparapu Raju, a well-known inventor in the Warangal district, has now come back with Light Dependent ...
