Introduction to Engineering Process. Module Objectives. define the concept of ‘Control System’ identify the main elements of a control system and explain the role of each element differentiate between the control system types
Control Systems are used
Systems and Control Technology is about making products or systems that combine parts or components.
Automatic night lamp
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.
