H2OnTHeGo (post4)

Previously I've said that I couldn't figure out how Bluetooth worked, this time around, I've decided that would be my next project.
Basically, Bluetooth is a technology that allows for the transmission of information between devices over a short distance using radio waves, once device being the "master" and all connecting devices being "slaves". For reference, a master device is often a phone and slaves are things like GPS, radio, ect. A group of synchronized devices is referred to as a piconet, where they all share a frequency hopping pattern determined by the master device. In my case, the bottle cap would be the master and the bracelet would be the slave device.
There's a bunch of technicalities that I don't think anyone would be interested in, but the gist of it is that each device needs to have sensors (usually located on the battery) that can send and receive the signals being sent at the particular frequency the master device sets. In application to my water bottle, sensors will have to be placed on the battery in cap as a strip and on the coin batteries in the silicon bracelet.
As a side thought, it would seem that the bracelet wearer would have to be near the bottle in order for them to remind the user to drink at the same time, so in order for the product to be practical the two parts of the bottle should run more separately than dependently.

Setbacks were minimal this time because information is so widely available over the internet! Yay! Although the tests were sometimes hard to read because of all the tech-y terms that I did not know. The terms were easy to search up though, so that was fine.
Looks like the project is coming to a close. Thanks for reading :)
