Steps
- Build a quarter-car rig with the mass sliding on the linear rail over a spring and damper.
- Mount the accelerometer on the mass and wire it to the Arduino.
- Drop-test the rig from a fixed height and log acceleration.
- Try several spring and damper combinations.
- Calculate peak acceleration and settling time and compare ride quality.
- Chart the responses and document the best setup for your portfolio.
