EE Data Collection Source Code

This program uses an encoder to measure the rotation of a swinging arm

Data Collection Procedure (Device Screen Captures):

Step 1: Pull Back Arm

• The arm needs to be pulled back until its pressing the button

Step 2: Prompt to Release Arm

• 75: encoder measurement in degrees
• 1: the arm is currently pressing the button
• Data collection starts the instant the arm is released

Step 3: Data Collection is Complete, Prompt to Save Data

• Once the oscilations have settled near 0 degrees, the data collection stops
• Prompts to save colllected data by pressing the right button

Step 4: Notify that the Program was Saved

• Data was successfully saved to .csv (comma separated value) file
