Creating an xor and xnor gate using only resistors, spdt/spst switches, and red LED diode.

[johndoe7777]

Hello I am doing a simple project, where I have to create the logic gates using only the items listed. I have created a not,and,or,nand and nor gate thus far. However I am stuck in creating the xor and xnor gate. I figure I have to use spdt switches, but I do not understand the concept. Thank you

Hello,

Well an spdt switch is a switch that has 2 inputs and a common output. The siwtch switches between one input and the other always refering one as the output. Also, I do not know the constraints of your project, but you should be able to create ANY type of gate from a conjunction of NAND gates.

Best of luck,
