Hi all, first time posting here, so let's see what happens.
My problem is this:
I am designing a control panel with 7 toggle switches that control-via relays-the availability of power to 7 outlets. On the panel there is to be 2 7-segment displays. One will show how many devices are plugged into the 7 outlets, and the other how many are currently drawing power. What logic would I implement to do the count in this scenario?
My first idea would be to use a pulsing IC to poll the outlets. My second idea would be to measure resistance per outlet and return how many are above and below a certain threshold. But, both these ideas rely on returning a count that I can feed into a 4511. Any ideas?
