Here's what i'm trying to do : I wish to deploy my parachute in my water rocket ...
I had 2 ideas.. the first one is not the i prefer but a alternative if my second one is impossible..
Idea 1 : Would be a servo that move after a specific time .. Example.. as the rocket launch, the timer start, at 10 seconds the servo move 179 degree, what deploy the parachute.
What i dont like about this idea.. is that the flight time might change each time.. so 10 seconds could be 12 next launch.
Idea 2 : Again a servo, but this time.. no timer, but instead with the help of accelerometer ( i think ) when the rocket start to move.. it wait until apogee and than it trigger the servo witch deploy my parachute..
I have been looking around and just not to sure what i should buy.. To take in consideration .. my ID (internal diameter) of the rocket is 40mm, and i think a Arduino uno 3 is larger than that ? (somewhere around 53mm)
I dont know much about arduino product (else than the 3D printer i had) so not sure i could do it with a other arduino type board than the uno 3...
If not possible with something else.. im willing to change my rocket tube seize to fit a uno 3.
Is any one able to guide me through my experience ?
Tank you ;)
