Sphero Workshop
===============

The goal of the workshop is to introduce basic programming and logic concepts through fun activities with Sphero.

Technology
----------

We use Ruby and Macrolab depending on age and prior programming experience. We have mobile devices (iPads, iPad minis, Nexus 7 tablets) to run the Macrolab application. We have Mac Books with Ruby 1.9.3 for Ruby programming with Sphero for older kids and those with more experience and/or interest in Ruby development.

# This file demonstrates a Caesar cipher
#   There is an encrypt function for encoding plaintext into ciphertext
#   and a decrypt function for converting ciphertext into plaintext
#

# given plaintext and key, return encoded ciphertext
def encrypt(plaintext, key, letters)
  plaintext_as_numbers = []
  # Represent each plaintext letter as a corresponding number

# This file demonstrates FizzBuzz in Ruby

  puts "FIZZ" if number % 3 == 0
  puts "BUZZ" if number % 5 == 0
