Finished 2DOF 12V DC wiper arduino playseat

[RacingMat]

Why would you need braking?
Nota: with Hbridge, the braking is only dynamic braking, not static braking.
When coils are shorten, the DC motor brakes under magnetic effects.
Warning, in this case, you have to dissipate more energy (heat)...

Gathering the Arduino codes, describing them, pointing out pro and cons is a lot of work!...
Which one is the best?
- the quickiest?
- the one with more functionnalities?
- the simpliest? (probably the code I posted)
?...

hey,

A little question: how can a 24v motor work when there's just 12v connected.

[RacingMat]

hello,

they are simply turning half speed and torque
but with this recipe (smolka + 12V + 60mm levers) you have enough

24V is more expensive to drive

Hi all,

i followed step by step the tut. Many Thanks !!!

I've got a working 2dof since march.

Then 3 weeks ago it happened that i had to format the 2 pcs.

Now i can't get the whole 2dof working.

I'm using rfactor , it seems that x-sim extractor and x-sim converter does't receive any axis information.

Any idea on how to debug / fix this issue ?

[RacingMat]

woh! congrats for having finished a whole dynamic sim!!

did you reinstall the same game and Xsim versions?

[proextremo74]

Hi,

thanks for replying.

I installed same version of rfactor and downloaded xsim from website.

Arduino is working fine.

Indeed it responds on :

datapacket sent on simulator start

When i run both converter and extractor i see they're connected, but i can't figure out if i'm receiving axis information from the game.

How can i debug it ?

Hiii Racing Mat

at first, sorry my poor English.

I continue producing 　my　sim machine with your threads about half year.



Now I have a trouble////


I try the First serial tests without Xsim follow the instruction of You .

**************************************************************************************************************
Not connect the pot and motor, manually turn the pot,I can stop the motor.

then,
connect to the motor.

in the Serial monitor, send " R7FLAE " ------ left motor move a little.

then send "R7FL7F"----------it move the playseat in horizontal position

I think this is normal behavior.


but next string

R64L64
R3FL3F
R01L01 (max !!)

first "R64L64" right motor turn oneside endless!!!!


My question is How write multi strings in the Serial monitor?

Is My wireing wrong?

Hey,

How/were do you connect your emergency stop?
Do you need 2 computers, does it work with one?

@Proextremo74: did you sort out your extractor problem? you should see the graphs moving while receiving the data from the game...

@Fledge: you cannot send multiple strings... you can send a long string but anyway arduino will only decoding the first characters received
I can't see your wiring clearly... did you manage to find the solution?

@arne :
I connected it on the PSU unit: it's the "main" switch that trigger the PSU
but it could be on the output of PSU but you have to deal with higher currents and it requires a stronger switch.

Single computer setup is fine! but you need to Alt-Tab if you want to change some setups in Xsim

Hi, I am just starting a 2dof sim following your guide here. Thanks for all the detail.

I was looking at your motors and I noticed there is a black plastic/rubber part, that inside this is white connector with three prongs. This is actually a hall sensor!!! Or somthing similar. You could use that directly and not use a pot. Thats what plan to do if I can figure out how to hook it up to arduino and change the code.

Anyway I thought I might mention that. It could actually save some people some money if their motors already have the sensors inside. I think its only used motors you will find with sensors.

Im thinking of buying these motors which are new but dont have the sensor. You have to buy it seperate.
