  * Project 1: get a functioning LED on GPIO pins utilizing command line approach
  * Project 2: replicate functionality, in a C program
  * Project 3: rig up 4 LEDs, write a C program that makes a binary counter with the LEDs
  * Project 4: wire together 2 RiPis--- one "counts" and sends the signal to its peer, its peer receives signal and outputs to LEDs accordingly
  * Project 5: telegraph-- utilizing an external switch, one RiPi sends signal to another, which lights up its LED
  * Project 5 overdrive: rig up contact switch for authentic morse code reception (simple electromagnet?)
  * Project 6: telegraph translation: in addition to lighting up the LED, parse the incoming message and display (character at a time) to STDOUT
  * Project 6 redux: long distance telegraph-- run a much longer cable... send and receive telegrams from across the room (or hall).
  * Project 7: contemplate a telegraph network... how would we enable a sender to select a recipient and send a message? (think about switching and relaying)


=====Week 1=====
  * Assemble Raspberry Pis
  * Get raspbian images on SD cards
