Proteus Circuit LED does not work
Second it's not clear what is your supply voltage, a led in simulation won't work in one case - the current is too low. … If you have a led with a voltage drop 2V is requiring minimum say 5mA and you are supplying 3.3V then in case you put an resistor 10K your current will be (3.3-2)/10K=0.13mA. …
