Introduction to Engineering Process
Control Systems are used
Systems and Control Technology is about making products or systems that combine parts or components.

when the LDR is exposed to darkness, it has maximum resistance. Therefore, the voltage drop across the LDR increases (>0.6V) and the transistor turns on which lights the LED. When it is bright, the LDR has least resistance and therefore the voltage across it is low (<0.6V). Therefore, the transistor is off which turns the LED off.
