This is a FUN talking BuildaBot for the official BBC micro:bit V2 where you get to build your VERY OWN TALKING BOT FROM SCRATCH!

# from us and will add what it learns into the
# database or db and when it loses power

This is a little itty bitty baby BuildaBot that only knows how to respond to "hi"
or "hello" so this is a great chance to teach it everything you want by typing the word
"teach" and then it will prompt you for a trigger word or words and then a response and
it will LEARN FROM YOU!
*** NOTE *** Make sure your trigger word or words do not use any punctuation of any kind when teaching the bot.
YOU: hi
BOT: Hi to you!
YOU: How are you?
BOT: I do not understand. Please type the word "teach" to teach me.
YOU: teach
BOT: Type Trigger Word/Words - Response: how are you - I am great thank you!
YOU: How are you?
BOT: I am great thank you!
Our little friend will forget what it learned when it loses power or gets reset however this is a GREAT opportunity to learn a little Python and type in some things we would LOVE our little friend to learn and keep in its little brain forever!

YOU: How are you?
BOT: I am great thank you!
Great job! You permanently taught little baby BuildaBot something awesome! Now you can continue step 10 over ande over as many times as you like to keep building its knowledge base. In the process you are also learning a little Python as what you just edited is called a Python dictionary where you get to add key and value pairs to teach our little friend ina very FUN WAY!
