Arduino Code for Fan Speed from Dashboard

I got mine half working and havnt had time to try anymore. It's hard when you can't code but it must be pretty simple for someone who knows how

I saw your video, it's not perfect but at least it works. You did it with the codes that you share right? What are you using... Arduino Uno and Monster Moto or something else?

Yes using ARDUINO and MM however I had problems with power constantly out putting through the MM so the fans always trying to spin. Maybe a dodgy MM or something but always a constant voltage did my head in in the end so gave up. May try again to sort it when I get back to my rig.

Maybe I need to use a different h bridge for it I have no idea. I am useless at coding so don't really understand it.

Guys this is the easiest way to drive a fan, with an Ard.


or even easier , its all on one pcb.


As you can see it will drive a fan , up to 60v at 20amps.
And is driven by one PWM pin , higher the value on the pin the faster the fan spins.

Or an RC driven code like my Model code can be modified to run a RC EC brushless controller to run a little but powerful fan too.

eaorobbie,
can you modify your "RC model" code for us. I can not code or modify.

I have a RC brushless motor and ESC combo pack that I used on my rc buggy, and I am planning to put a rc model propeller on the motor in order to have the wind simulation on my RollerCoaster sim.
Here is the wiring of the hardware, I need codes for Arduino to work with Game Dash.
I think that once having the codes this hardware configuration will be the easiest and best way (as you mentioned) for wind (fan) simulation because they are cheap and there are many models for application needed as power, dimensions, long life, high RPM etc...

Ok i am soon to try again with my fans. I have ordered 2 of the freetronics mosfet boards and I have 4x 545 12v RC motors. I think I have the code which will work without using the MM so I will keep you all posted. Fingers crossed it may work this time lol

Hope that you will succeed, I will cross my fingers for you as well.
Waiting for your reply soon.

Ive done it Ive Done it !!!! Thought I would have 1 last try with the MM and I got it working, well just about lol. Still cant get the bloody thing to stop when the speed is at 0, still slight input causing voltage making the motor whine constantly.

Does anyone know a shutdown command from the GameDash as the fan carries on trying to spin once I leave the game. @value1 @yobuddy

Thanks to @eaorobbie for the original code that Ive just added to.

This just works fine for no limits but other games I have no idea until I try it out.

@Mamati I know you were interested in this so here it is


#define BRAKEVCC 0
#define CW 1
#define CCW 2
#define BRAKEGND 3
#define CS_THRESHOLD 100

int inApin[2] = {7, 4}; // INA: Clockwise input
int inBpin[2] = {8, 9}; // INB: Counter-clockwise input
int pwmpin[2] = {5, 6}; // PWM input
int cspin[2] = {2, 3}; // CS: Current sense ANALOG input
int enpin[2] = {0, 1}; // EN: Status of switches output (Analog pin)
int statpin = 13;


// This just works with one variable from the Game Dash.
int Speed ;
int SpeedGameDash = 0;

int bufferArray[4];

void setup()

{
pinMode(11,OUTPUT);

Serial.begin(9600);
pinMode(statpin, OUTPUT);

// Initialize digital pins as outputs
for (int i=0; i<2; i++)
{
pinMode(inApin, OUTPUT);
pinMode(inBpin, OUTPUT);
pinMode(pwmpin, OUTPUT);
}

// Initialize braked
for (int i=0; i<2; i++)
{
digitalWrite(inApin, LOW);
digitalWrite(inBpin, LOW);
}
}


void loop(){
//****************************** READ DATA FROM SERIAL ******************************

}

void motorOff(int motor)

{

digitalWrite(inBpin, LOW);
}
analogWrite(pwmpin[motor], Speed);
}

void motorGo(uint8_t motor, uint8_t direct, uint8_t Speed)
{
if (motor <= 1)
{
if (direct <=4)
{
// Set inA[motor]
if (direct <=1)
digitalWrite(inApin[motor], HIGH);
else
digitalWrite(inApin[motor], LOW);

// Set inB[motor]
if ((direct==0)||(direct==2))
digitalWrite(inBpin[motor], HIGH);
else
digitalWrite(inBpin[motor], LOW);
analogWrite(pwmpin[motor], Speed);
}
}
}

void ReadData(){
if (Serial.available() == 4) { //if 4 bits available in the Serial buffer...

int i;
for (i=0; i<4; i=i+1) { // read and label each byte.
bufferArray = Serial.read();
}

if (bufferArray[0] == 'S'){
SpeedGameDash = ((bufferArray[1]-48)*100) + ((bufferArray[2]-48)*10) + // Take values 1-3.
((bufferArray[3]-48)*1);
//Serial.print("You have set the Speed to a Value of:");
//Serial.println(SpeedGameDash);
}
}
}
void CalcPWM() {

if (SpeedGameDash > 0){
int oldSpeed = Speed;
Speed = map(SpeedGameDash, 0 ,50, 0 , 255); //change the "50" value to the speed of your choice
if (oldSpeed != Speed){
//Serial.print("Fan Speed set to :");
//Serial.println(Speed);
analogWrite(11,Speed);
}
}
}



If I can iron out these few problems it should work on pretty much any game with speed output. All we have to do is change the 50 value above to a speed that you want the fans to be on full speed. Simples really I just didnt understand it think I figured it out by luck

Anyways hope some peeps make use of it

Thanks @yobuddy for the reply I'll have a look see what I can do with it but my coding is pretty basic lol

Maybe I need to put a 10k resistor on pin 11 to ground perhaps that will work ? I will try later

Very nice @SilentChill , I am looking forward to trying it but I have to buy first of all an additional Arduino and MM.
I will let you know about my experiences.

Hi all got it working perfect now Motors shutoff as they should when the speed is at 0, no more voltage going to the motors YIPPPPEEEEEEEEEEEE.

Heres the code

}
}
}


This is the line that I needed to put in so simple yet so frikkin hard when you have no idea what your doing lol

if (Speed=0 , motorOff);

Anyways I did it all by myslef im well proud of me, the wife doesnt care but i do



Woohooo no stupid electrical whining noises anymore !!!!

Videos to follow soon !!!

@SilentChill It is awesome but I could't try it because I had problem when loading your codes.
I checked your code on Arduino after pasted it and Arduino mentioned lots of errors.
Maybe the error is caused because I didn't wire the MM to Arduino yet...could it be reason?
If yes what is the wiring between Arduino and MM?
If no what could be the problem?

MM is connected straight onto the top of the Arduino no wiring needed part from the power. The code should work fine ??

Can you tell me what errors you are getting ?

I named your code as "Fan" on arduino library
Here is all error message

Ok possibly the formatting has been screwed up by the forum I will upload the file when I get home if I can

I have changed a couple of things as well . we just use the game dash to control the speed for different games as it should do No need to change the code on the Arduino once it has the code on it. I didn't quite understand it but I do now lol I will create a new thread soon and upload the file to that.

I have created a new thread and attached some screenies and the code
