Hello,
Currently im doing a circuit about fading out light. I managed to get the desired output that i want. The voltage across the lamp will drop slowly around 6-10 secs depends on the value of capacitor. The problem is about representing the discharge of capacitor / lamp voltage vs time using the proteus graph. The graph can't capture the voltage drop of lamp when the switch being switch on and off.
Can anyone help me out?

hi adzlan88
it is better u post ur proteus circuit here that anyone can help u better

ok here is the circuit, the problem is, i cant display the voltage drop across lamp using graph when it is fading out (switch off) i mean from the voltage at 11.6V and dropping to 0.xxV something.

i do not understand how will you get fading effect with this.. you're using a transistor to control Lamp as you know transistors work as a switch so i do know how fading comes in picture here.

for the circuit above, i got it from a website and here's the link.
http://www.electronic-circuits-diagrams.com/carsimages/carsckt3.shtml

From what i understand, when the switch is off, the capacitor discharge and voltage across it drops, same goes to voltage across vr1 and the base current at transistor also drop slowly, therefore the current through the lamp also drop slowly. I tested it on proteus and it seems to be working. Please correct me if im wrong.

But the main problem is to represent the Voltage dropping from 11.6v-0.70v using the graph in proteus.

hi adzlan88
i think graph is correct
i never make a graph in proteus for graph i alwaz use a livewire electronic software
here i am uploading a livewire file u can match it with proteus i think ur going to confusing at some point

u can download setup from here

majoka thanks for the circuit, thats what i want , coz i tried in proteus oscilloscope it doesn't have any ground/negative terminal for me to check the voltage drop across the lamp directly.

in Proteus oscilloscope there r just 4 channels that can be directly used there reference is ground by default
