I am trying to turn on/off some circuits from relays using a microcontroller. Each day at a specific time the circuit turn on and at a specified off time the circuit turns off. Each of the circuits is for each day. For example, day 1: circuit 1 turns on, day 2 for circuit 2, day3 for circuit 3, .. day 6 circuit 6 and then day7 circuit 1 and it goes on..
The connection is as : microcontroller -> relays -> external circuit
On the software side I will program the microcontroller to turn on/off the circuits at the respective date. The on/off times will be specified by the user.
But I want to be able to do it on the hardware side such that when circuit 1 is on, all the other circuits are not getting power and hence they will not turn on. When one circuit is on, the rest should be off. I want some kind of redundancy on the hardware side also.
I want to have some ideas on how i can achieve this task.
Thank you
