1. The problem statement, all variables and given/known data 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 . 2. Relevant equations 3. The attempt at a solution Is it possible to form a digital logic circuit using diode and resistor?
