Question Arduino Simtools with Relay

Greetings,
I would be interested in making a very very simple low budget motion for my home for the kids. My idea of making this rig is as follows.
I would want the Arduino board to work the same as its working for the motors in the famous project which is already on this website, the only changes I would be interested in making is, there will no motors attached with this project. I would be using an Air-Compressor, Solonide, and relays to push up and down four bellows.
These four bellows will be located under a platform and on the platform would be my seat. The Arduino will be sending the commands to the relays to activate and when the relay is activated, the solonoide will activate making the air from the compressor to release and thus making the belows go up and so the platform along with the seat will go up. So I need 4 relays to be operated by arduino using Simtools.
Kindly help me with your suggestions and will try this out as this is going to be in a very low budget.

Thanks and regards,

Sebastian Alexo Fernandes

Yes something similar to the above project, but would be using Bellows instead of Pistons. Could you please help me with the code as I m very new to all this stuff and Im trying get into it.

This an Uno
and a 4 channel 5v relay module

and Have uploaded this sm3 code on UNO and want the relays to activate in simtools

Below is the code of sm3 in short form

Code:

//****************************************************************************************************************
// SMC3.ini is basic Motor PID driver designed for motion simulators with upto 3 motors (written for UNO R3)
//         
//****************************************************************************************************************

// Set to MODE1 for use with a typical H-Bride that requires PWM and 1 or 2 direction inputs
// Set to MODE2 for a 43A "Chinese" IBT-2 H-Bridge from e-bay or equiv

#define MODE1   

// Uncomment the following line to reverse the direction of Motor 1.

//#define REVERSE_MOTOR1

// Uncomment ONE of the following lines to enable analogue input AN5 as a scaler for the motion values.

// #define ENABLE_POT_SCALING
// #define ENABLE_NON_LINEAR_POT_SCALING

// Uncomment the following line to enable the second software serial port.
// NOTE: This is currently not working - leave commented out until fixed!!!

// #define SECOND_SERIAL

//    COMMAND SET:
//
//    []                      Drive all motors to defined stop positions and hold there
//    [Axx],[Bxx],[Cxx]         Send position updates for Motor 1,2,3 where xx is the binary position limitted to range 0-1024
//    [Dxx],[Exx],[Fxx]        Send the Kp parameter for motor 1,2,3 where xx is the Kp value multiplied by 100
//    [Gxx],[Hxx],[Ixx]        Send the Ki parameter for motor 1,2,3 where xx is the Ki value multiplied by 100
//    [Jxx],[Kxx],[Lxx]        Send the Kd parameter for motor 1,2,3 where xx is the Kd value multiplied by 100
//    [Mxx],[Nxx],[Oxx]        Send the Ks parameter for motor 1,2,3 where xx is the Ks value
//    [Pxy],[Qxy],[Rxy]        Send the PWMmin and PWMmax values x is the PWMmin and y is PWMmax each being in range 0-255
//    [Sxy],[Txy],[Uxy]         Send the Motor Min/Max Limits (x) and Input Min/Max Limits (y) (Note same value used for Min and Max)         
//    [Vxy],[Wxy],[Xxy]         Send the Feedback dead zone (x) and the PWM reverse duty (y) for each motor
//    [rdx]                  Read a value from the controller where x is the code for the parameter to read   
//    [ena]            Enable all motors
//    [sav]            Save parameters to non-volatile memory
//    [ver]                     Send the SMC3 software version
//

Yes this is what it should be like, I was trying to find this type of content on this website but was not able to, But still I am look for the arduino code for the same
