Personal short projects with Arduino

Higlights:

lowMemWaveform:

A cheap, low memory digital oscilloscope that can display 
readings in a small display. Manipulates low level 
registers on the chip to sacrifice resolution for 
magnitudes larger sampling frequency.
Instrumentation amplifier not included.

pong_v4:

A two player game as an exercise in object based 
programming. Uses oled display, and potentiometers as 
controllers.  Increasing difficulty over time.

signal, and displays heartrate on LCD screen.
--------------------------------------------------------

CYOA and Code_writer:

A choose your own adventure displayed on LCD, with 
turning pages, handling debounced button inputs, 
and several choices. Code_writer converts text 
input into sourcecode for CYOA to speed up the 
programming process.

velostat3:

A piece of code I often reused when a project needed
pressure sensing. Usually with a piece of velostat
