Covered the way Bluetooth (named after a scandawegian pirate king Arrr!) works. There was talk about stacks and more acronyms than should rightly be introduced at one time. I feel fuzzy about this stuff (bad war flashbacks to Data Comms at uni). I did get the stuff about AT commands and their syntax (a good this to get). It's necessary to get the Bluetooth modules talking to each other for the project.
BLUETOOTH! We took a pair of Bluetooth chips (master and slave) and got them set up to send and receive messages. Much of the lab time in the morning was taken up with planning the video our team is making.We then only just had the circuit set up to send a signal from a soft potentiometer across Bluetooth to a buzzer on the other circuit when time was called D'oh!

Interesting Stuff Learned
Evening Activity: Cryptography Challenge. I have done this challenge twice and both times I have completely failed at it. I don't think I'm going to be working for ASIO any time soon. There are a bunch of teams who have a tutorial to follow and a two computers and one is meant to be used to decrypt existing codes and one should be used to write encryption functions. I had a really good idea for a decent encryption but based on tiredness, logic errors and lack of proficiency with Python I got it debugged just after the closing bell. (2 hours of frustration!!) I don't deal with that level of frustration well. Congratulations to all the amazing teams who managed much more than I did.
