Instead of changing microcontrollers the decision was made to use serial commands but reformat them so they can be copied from Arduino's serial terminal and pasted into a spreadsheet. A serial terminal with the ability to export a .csv file may be researched in the future. If a reading is taken every 15 seconds there would be 5,760 readings in a day which could exceed the amount of data able to be stored in a terminal window. This can be tested quickly by running very fast samples to capture 6,000 readings in minutes. Shorter sample periods may also be feasible.
Measuring the revolutions was more difficult than expected. The first program used a while loop to halt the whole program until readings were seen on each station. Changes were made and the whole function was eliminated in favor of a function which operated transparently. With no wind turbines attached the program was tested by manually spinning posts to generate voltage and a tachometer frequency. Output was recorded in Arduino's serial terminal and graphed in a spreadsheet program.
No more revisions will be made until necessary. This phase of the wind turbine project will be considered COMPLETED. Testing for the turbines will be done in Wind Generator Turbine Design Tests. Construction of turbines will also be done there.
