Is it possible to implement this circuit operation?

Homework Statement

When switch A is turn on , LED 1 will light up When switch B is turn on , LED 2 will light up. When one of the LED is turn on , all other LED will not turn on. When the LED is turning on and if you are to press another switch , it will have no effect at all. what I mean is no other LED will turn on

In this project , I am only allowed to use the following component.
opamp , zener diode , led , resistor , capacitor , p or n mosfet , NPN BJT or PNP BJT , diode , temperature sensor , LDR , speaker , trimmer , switch(normal) , pusb-button switch , infra red emitter , red detector
.

Homework Equations

The Attempt at a Solution

Is it possible to form a digital logic circuit using diode and resistor?

 

[Daz]

Yes - it's called RTL or resistor-transistor logic. (wikipedia has it covered.)

Uh ... Daz, how to you jump from the question about diode/resistor logic to resistor/transistor logic? They are not the same thing.

No, but since you are allowed to use transistors you don't have that problem.

I misread - that's how. Oops. Anyway RTL or DTL would do.
