THANK YOU ALL VERY MUCH for your help.
i finally finished the project. i used an Arduino Leonardo, 2 rotary switches, and a custom made board for 2 relays, a 24DC relay.
- multiple position rotary switches for setting the number of steps in each mode, photo1.
- board with 2 relays since i couldn't find a single relay with 3 positions. i used 2 to give me closed circuit for each position of the switch on the press that controls in which mode the press operates, photo 2.
- 24DC relay for giving input to arduino whenever the press is on up/ready position.
i have set up the arduino to use the INPUT_PULLUP method on all inputs so on integer level i read 0 for LOW, and 1 for HIGH. as explained here constants - Arduino Reference . i found this method to be very simple since i can keep the things simple and just send ground to each pin that i want to read input.
sorry for not preparing in detail on the DIY. i think that the information provided will provide the necessary explanation on how the solution worked out. when i have time i will be preparing a step-by-step DIY and post it.
and here is the code:
#define P1 2 //defining inputs of the positions on the rotary switch
#define P2 3
#define P3 4
#define P4 5
#define S1 6
#define S2 7
#define S3 8
#define S4 9
const int buttonPin = 12; //the input to read the position of the press
const int ledPin = 13; //test led
const int s = 10; //relay to position mode
const int p = 11; //relay to pressure mode
int buttonPushCounter;
int buttonState;
int lastButtonState = HIGH;
int HP1;
int HP2;
int HP3;
int HP4;
int HS1;

int stepspressure1;
long lastDebounceTime = 0;
long debounceDelay = 200;

int HS1 = !digitalRead(S1);
int HS2 = !digitalRead(S2);
int HS3 = !digitalRead(S3);
int HS4 = !digitalRead(S4);
int stepsposition = HS1 + 2*HS2 + 3*HS3 + 4*HS4;
int stepspressure = HP1 + 2*HP2 + 3*HP3 + 4*HP4;
if (stepspressure1 == 0 && stepsposition1 == 0){

if (buttonState != lastButtonState) {

if (stepspressure1 < stepspressure){
stepspressure1++;
digitalWrite(p, HIGH);
Serial.print("pressure ");
Serial.println(stepspressure1);
if (stepspressure1 == stepspressure){
stepsposition1 = 0;
digitalWrite(p, LOW);
digitalWrite(s, HIGH);
}
}
if (stepsposition1 < stepsposition){
stepsposition1++;
digitalWrite(s, HIGH);
Serial.print("p ");
Serial.println(stepsposition1);
if (stepsposition1 == stepsposition){
stepspressure1 = 0;
digitalWrite(s, LOW);
digitalWrite(p, HIGH);
}
}
}
lastDebounceTime = millis();
lastButtonState = buttonState;
}
}
}
please feel free to ask any additional information. i'll answer as soon as i have time
