Programming was added to trigger relays depending on the tag being scanned. A preprogrammed timer was added for each tag. Before any relays were programmed, the coding was changed so everything operated out of arrays. This was done to make it easier to trigger the outputs using functions as opposed to makign a unique block of code for each output.
The difficult part turned out to be making the relays turn off after a set amount of time. This was accomplished by regularly calling the same function that activated the relays but adding a section which checked the state of the relays against their timers.
One of the tags was problematic. At first it seemed to be a problem with a large timer value but the issue followed the tag when its function was swapped with another tag. This will require more examination.
The rest of the posts for this project have been arranged by date.
