Probably you are driving too much current through the motor chips, they overheat, shut down, cool off, and recycle. Get a meter with a 2A scale and put it in (...)

| | Vector2X compass accuracy?

| Could anyone tell me what type type of accuracy/precision you get from the vector2x compass? Does it just return n,s,e,w,nw,ne,se,sw, or a byte? Is there a datasheet somewhere on the web? Thanks for the info! -=Fred Cass=- (27 years ago, 15-May-97, to lugnet.robotics.handyboard)
