Hey all,
I'm having trouble with this homework problem from my digital logic class.
A home security system has 15 sensors that detect open doors and windows. Each sensor produces a digital signal 0 when the window or door is closed and 1 when the window or door is open. The control for the security system is a microcontroller with eight digital input/output bits available. Each bit can be programmed to be either an input or an output. Design a logic circuit using dual 8-to-1-line multiplexer that repeatedly checks each of the 15 sensor values by connecting the sensor output to a microcontroller input/output that is programmed to be an input.
I would love to show you all the progress I have made, but I can't even figure out where to start. If someone could just point me in the right direction that would be fantastic.
