Hi everyone, I think this topic will be interested for someone who want to do some DIY like me.
I'm trying to do the tilt mirror for my car and really want to do by myself.
I thinking the direction to code, just said the direction is learning the position of tilt depend on the driver because some time I will borrow my car for someone, then they will adjust the mirror accordingly, so the learning of mirror tilt up and down are required.
The learning will be the time delay for tilt up or down and save it then when put it into the reverse, will be tilt accordingly.
Just said like that, but I do not know the direction how I can go
So, could you please give me any idea, direction how to do as above mentioned or if have any idea for this solution, it would be help me a lot and it appreciated.
Thanks you so much
I moved your topic to an appropriate forum category @pctrung.
In the future, please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.
This is an important part of responsible forum usage, as explained in the "How to get the best out of this forum" guide. The guide contains a lot of other useful information. Please read it.
Thanks in advance for your cooperation.
What have you tried and what were your results causing you to ask for help in doing it yourself.
Hopefully you understand what you are in for with the automotive electrical system. Here is some information.
There is many good app notes such as AN2689 by ST on automotive electronics. reading it will help you a lot.

I thought about it too, and also using timers, but concluded that it isn't such a good idea. The main problem would be that the little motors in the mirrors would have to do the same job in the same time every time. If they don't, you will be forever fartarsing about with it - every time. Another is that, if you make any other adjustment for any other good reason, you will have to go through the parking procedure all over again.
If it can be made at all feasible, I guess it will have been done by now. It is just the sort of thing Saudi Arabian princes would want on their Ferraris and pay serious money to have it. Rather like those pop-out door locks on Range Rovers.
If it has been done, I would guess there would be stepper motors involved.
On your side mirrors?
yes, on reverse mirror
thks so much and noted
To switch between night and day mode?
Many thanks with your high light
Hi Paul,
In first step, I'm designing for the PCB first
As said that, I'm trying to do it but it was stuck in direction of programing, and would receive the idea to do it
it need to tilt the mirror when the gear put into the reverse
Do you know for a fact that the car computer does not control the mirror position when you operate the switches?
Hi Paul,
Yes, the ECU does not control the mirror position, it will be control by the switch at driver side.
So I will control some relay for tilt mirror, it will not affect to ECU
Good to know! Makes it much easier. Please don't use those crappy relays in blue boxes, but some reliable brand relays that are still protected from dust and dirt.
Hi Nick,
You are not wrong
But sometime the people also want to do some things for upgrading so far and do it by themself, it would be happy
For sure, it not much current when the motor in operation, it small DC motor for forward and reverse operation.
Provided attached is the circuit for the switch control of tilt mirror, the motor will be run when the switch is change over and active.
So I thing I will add some relays to switch and control relay by arduino.
In my opinion, it is necessary to set the time for the down and up tilt of the mirror according to the driver's vision to be able to see more clearly behind.

Can someone help me how to learn and store the value of timing then it will be take out for using.
I do not know about direction how to go
Thanks you very much for your support
Mirrors I worked on had feed back giving the mirror position. Have you checked into that and if so can you get its values?
thanks for your reply, but actually my car mirror without the feed back their position that why I need to use with timer to know the motor need how many second to reached positioning correctly as driver require for tilt down and up, then store this value during the learning, then it will be take to use when put the gear into the reverse.
The way like this, but i do not know about direction how to program
