I got an accelerometer Monday morning and have been trying to understand it by prototyping with an Arduino. Got a little visual display running in Processing to test the control system. In this demo, tilting the accelerometer adjusts the speed of the ball on the screen.
Takeaways:
- We need to set a "dead zone" where the boat won't drift left or right.
- We need to have an indicator of when the controller is level.
- The accelerometer currently controls a fairly tight speed range - this might need to be expanded.
- It's a bit twitchy - expanding the speed range and then breaking it into discrete steps could help this.
