1) is bmp180 good enough for this task ?
2) I am going to use the delay function . Is there any better option ?
3) Will this idea give me speeds with accuracy ?
I am expecting that the rocket should go over 1 km and it should achieve speeds over 350 m/s . It should atleast have an accuracy of 10 m/s .
How many seconds do you expect to be flying?
This can't be a new problem. How do other rocket builders do it? GPS?
