Simulated Wind using MonsterMoto and ArduinoUno

[QUOTE = "Avenga76, post: 111433, member: 10691"] I tried a new MM and a new Arduino and still the same problem.I did not bother to turn on the fan, I just connected my multimeter directly.When I connect the Arduino, both show the 1.8v engine and when I start the game, both engines go up to 3.8v and stay there until I disconnect the Arduino.I do not know much mm but some things need loads to show the real voltage, sometimes without load the volts change ...


I just want to make sure I'm loading the code correctly. I'm using the Arduino IDE and I use this to load the .ino file, so I selected the correct communication port and click the upload button, is all I need to do? No other steps? It says "Compiling sketch" and "Completed upload" so it looks like it is sending everything okay. [/ QUOTE]

I'm sorry, I did not know the rules ... I've already done one more post, before I see your alert, I'm sorry, it will not happen again.

@Fernando Romão Filho check this line on the .ino:
// This just works with one variable from the Game Dash.
int Speed ;
int SpeedGameDash = 0;

it has to be :
int SpeedGameDash = 1;

This happened to me for a week or so, until I found out.

first of all Make sure the fans you choose work directly through the 12 volts by the controller. See this example

Hi,

I have problem with connection, possibly with power supply.

At the beginning, I got original Arduino and MotoMonster and SeaFlo blowers.

I didn't have any special power supply, so I used one from PC and connected it to main MotoMonster via Molex. On MotoMonster + went to +12V branch of the Molex and - to the ground on the molex.



It worked perfectly without problem.

I decided I will get proper power supply and do coils mod as well.

I hooked everything same as before, just added new power supply + coils, connection to power supply was like this:



It's 12VDC power supply giving 16,5 A max.

I turned it on, the blower started to spin, but there was burning smell so I turned it off immediatly, but it seems Arduino is burned. It's not possible to upload code anymore and power led isn't on when powered. It just gets on when I press restart on Arduino, that's all I can do with it.

Now this chip circled below and it's near area gets VERY hot once powered via USB:




I thought it was due to coils or something else (I got these - they look little bit different, they are made from multiple tiny strands and not from one thick one as shown on images form @Avenga76, but the specifications should be almost the same).

So I got another Arduino, and hooked it up without coils and even without blower to be safe, Arduino had uploaded program which has default speed set to zero, so it shouldn't do anything, but it burned Arduino same as before . PWM mode was set to 0.

If I plug in power supply with just the MotoMonster, both big chips on MotoMonster are cool.

Once I attach it as shield to Arduino (without blower connected) one chip gets very hot immediately (I can hold finger on it, but it's uncomfortable), the other chip stays cool.

Anyone has some idea what's going on? As it worked ok with PC power supply before. Do I have the connection to the power supply correct? It has +12 V and the other ports are named COM, which I found should stand for common and should be very similiar to ground.



Or this is the problem and I should connect the black cable to GROUND next to green/yellow cable?

I thought power from MM shouldn't go to Arduino at all. Also I have it connected to Arduino as shield and all pins are there, also those with +5 V and + 3,3 V, but it worked before with PC power supply, so it shouldn't be problem.

The MotoMonster is looking to work fine - the red led shines when connected to power supply. I don't know it it's ok or it could cause the trouble.

I'm now afraid to do more experiments and I ran out of Arduinos anyway, I will probably getting cheaper clones now to figure it out.

Anyone has idea what I did wrong?

Many thanks.

16,5 v its a overpower voltage. Maintain between 12 and 14 its a limit. WARNING, very important thing, just put a multimeter and take voltages from this power supply. Generally made in china, voltages and amper are instable and poor.

Dont conect "ground" cable, only positive and negative. Dont invert this position too.

@paulopsx2 Ahhh, I see now where I made mistake.

Before I was connecting servos, which has only +12 V and ground cables, and I got association from there, that black cable = ground.



But I see now that MotoMonster is + and - which should be connected to power supply.



It seems I bought wrong power supply, as it doesn't have minus at all, it has just +V and COMs, which are probably same as ground. This power supply is designed for powering LED stripes.



So I guess I need to buy power supply, that has plus and minus.

I have found this one from Meanwell, which is just 12,5 A and passive cooled, should it be enough or I need stronger one? Two blowers should take 12 A which is pretty close to the limit of 12,5 A this power supply is capable of delivering.

Stronger power supplys are actively cooled and like two times more expensive. For example this one.

Anyway one thing I still don't understand is, that when I connected it to PC power supply directly to molex connector to +12 V strand and ground, why it didn't burned the same way as with this power supply. Any idea?

Many thanks for help!

I printed a case for the arduino and moto monstershield that I had removed from my first version simu 2dof 12v

The case is just stuck

Server supply

interesting.... dont need a induction for blowers?

another solution

sorry I dont understand

To manage the wind

Hi guys,¨
i would love to make wind simulation for nolimits / assetto as well.
I would like to try blower NZXT FN200 (https://www.nzxt.com/products/fn) , because the parameters looks promising, it is very silent and i have one here accidentally
Can i use the arduino code in first post with this blower as well?
Also few pages ago you´ve been discussing any "PWM Modes" - i can not see any pwm mode settings in original code? Where can i change that and what pwm mode would you recomend for my setup (Arduino Uno + Moto Monster + NZXT FN200)..

I got simdash running already so no troubles there

Btw what power source shall i get for running this blower - according to parameters it drains 0,42A (i guess it is max) so for one fan just a small 12V/1A source should be more then ok?
Many thanks for info!
