Upcycling your own Message Bag
When we ended the previous chapter, you may have collected some information for improvements to the use of Message Bag. What it currently does is follow a process with four stages, including an initial sequence of lights to communicate that it is on, a scan-in or scan-out of a tag, checking the state of the tag and whether it is scanned or not, and then a response based on the state of the tag.
When using this prototype, although it functions well, there are a few issues you may have noticed. These iterations are related to the function or role of the prototype, not the aesthetics or look and feel. We can implement these iterations while it is still breadboarded.
For example, in the instances when there is a slight delay in the tag scanning process, I’m left confused. Is the tag recognized? Is it still scanning? Secondly, when the system is powered off and back on again, the tags I scanned are not recorded.
Did you also make these observations...
