Folks,I have a new project idea and want to do some ground work first.I have seen this:http://www.toysdownunder.com/arduino/acellerometer-lis302dl.htmlBut what is the difference between one of these and a "Gyro"?
you can't use it to measure changes in a boat's heading (because 'down' doesn't change when the boat turns left/right).
Quoteyou can't use it to measure changes in a boat's heading (because 'down' doesn't change when the boat turns left/right).Are you sure about that?
QuoteYep.When you rotate an object at a constant angular speed, which of the following has to be true:1) there is force on the object (thus it can be sensed by an accelerometer);2) there is no force on the object;3) all of the above;4) none of the above.
I'll pick A.
1) there is force on the object (thus it can be sensed by an accelerometer);
QuoteI'll pick A.You would be correct.
I'll pick A.Thanks folks for the clarification.
if an object is rotating at a constant angular velocity then there is no force being applied to it.
Acceleration is a change in velocity
have seen it with my own eyes.
