Added SD Card reader TODO: Verify if we need to use 3V3 or 5V for the SD card. If it's 3V, then we need to add in a level shifter between ATMEGA and the card.

Version 2_UPDATED_ADC Added in voltage regulators, power and programming headers, and bypass capacitors TODO: Still need to add in SD card reader circuitry. CHECK: Do we need to set AGND on the ADC to the sensor ground? Is the 0.5V regulator going to produce a steady reference voltage? What is the voltage for the strain gauges (UPDATE R2 VALUE WHEN WE KNOW)?

New board with updated ADC1256 from TI TODO: Redo calibration circuitry to be single-pot per bridge (REMOVE 1 pot chip), and add in 370 and 5k resistors as done in previous board versions TODO: Add in programming header, SD card reader, and voltage regulators.

Version 1 FINAL Nearly complete version of the first iteration of the strain gauge logger. TODO: Check SD card for validity. I have no idea how it's supposed to be hooked up.
