Hello World,
Im very new to this electronics field and im in badly need of some help. Im working on an home automation system. There are only 4 pins free on my 8051 device. Using only these 4 pins i should be able to control atleast 10 devices. The solution here is obvious, we should use a multiplexer, but the problem is; if i use a multiplexer i'll be able to use only one device at a time.. i should be able to control all devices at once.. can anyone please please help me, im in urget need of it..
Do we have something like multiplexer with memory .. like the multiplexer output pin will be active till we turn it off or something like that..
