This is the circuit used for the first modules in
the course and is developed from the initial introductory page as the
course progresses.
Note: It's
designed so you can program it in circuit using ICSP without removing
the programmer and its designed so you can go back to any course module
without changing the hardware again.

You'll also need a serial cable and 9-way serial connector and wall
power supply 8V or more (less than 20V - the higher the voltage the
hotter the 7805 will get).
