Hey guys.
I am an avid car enthusiast and i was wondering if i could get some help from you guys.
I have wanted to make my car a track day car and have some cool special features for my car.
On some track day cars they have a feature for the rear wing called air braking and DRS. The air Breaking is when the rear wing is almost straight up and down causing a lot of air resistance and slowing the car down for corning. The DRS is when the wing is flattened out and puts less down force on the car to make it faster in the straights of the track. And also just going back to the regular wing position after a while. I have an arduino uno. I would like to have it so that i can push one button and the wing goes to an air breaking mode, then push another button and change the wing to normal angle, and then another button to change it to DRS mode. I would also like three different leds to tell me which mode i am in. The wing is moved by a servo. If anybody could help me with writing the code/making the board that would be much appreciated.
The software will be very simple, but it seems to me that the servo is not a simp!e R/C one, so won't be controlled by the Servo library
is there any way of being able to do this with a servo then or do i need something else?
What is the servo?
How is it controlled?
I have the standard one from the arduino kit but a better one would be a traxxas water proof one that i have. and i dont know what you mean by how it is controlled.
Hi,
I have talked with a guy making an actual racing version of this. It takes a lot of force and a strong linear actuator to set the angle of the wing. A small "servo" will not do this..
What is your actual hardware?
Have you calculated the torque on the servo caused by the braking force on your spoiler?
No i have not but i was thinking a simple pully system to lighten the loads may help. This is why i came here to see what I need to do this.
Controlling an R/C servo with an Arduino is really simple.
There are examples to show you how included in the IDE.
Deciding if an R/C servo is suitable for your application isn't really the point of this forum - that's down to avid car enthusiasts.
Thanks for the advice.
Skip the hobby servo. You need a hydraulic linear actuator to deal with that torque and have usable speed. Porsches do this as a function of speed.
