        Complete description;
  • The first part of the circuit, before the sub-system, is a simple switching device using a transistor.
  • The sub-system compares the voltage from the next part of the circuit, to the first part of the circuit.
  • The last part of the circuit monitors the output from the LDR.
  • And the final part is the LDR and potentiometer (Light Dependent Resistor) whose resistance increase with light.

Testing the circuit;

                I tested the resistance that I would receive from the LDR when it was totally dark (810Ω), and when it was light (50kΩ).

Light Intensity

Resistance 1 (Ω)

Resistance 2 (Ω)

Average Resistance (Ω)














        Attached, as appendix 1, is the graph of the discharge of a capacitor.


        My final circuit meets the specification because the LED stays on for 13 seconds when the LDR detects some one is at the door.

        It is reliable.
